Electrocatalytic Proton Reduction by a Cobalt(III) Hydride Complex with Phosphinopyridine PN Ligands

Cobalt complexes with 2-(diisopropylphosphinomethyl)-pyridine (PN) ligands have been synthesized with the aim of demonstrating electrocatalytic proton reduction to dihydrogen with a well-defined hydride complex of an Earth-abundant metal. Reactions of simple cobalt precursors with 2-(diisopropylphosphino-methyl)pyridine (PN) yield [Co-II(PN)(2)-(MeCN)][BF4](2) 1, [Co-III(PN)(2)(H)(MeCN)][PF6](2) 2, and [Co-III(PN)(2)-(H)(Cl)][PF6] 3. Complexes 1 and 3 have been characterized crystallo-graphically. Unusually for a bidentate PN ligand, all three exhibit geometries with mutually trans phosphorus and nitrogen ligands. Complex 1 exhibits a distorted square-pyramidal geometry with an axial MeCN ligand in a low-spin electronic state. In complexes 2 and 3, the PN ligands lie in a plane leaving the hydride trans to MeCN or chloride, respectively. The redox behavior of the three complexes has been studied by cyclic voltammetry at variable scan rates and by spectroelectrochemistry. A catalytic wave is observed in the presence of trifluoroacetic acid (TFA) at an applied potential close to the Co(II/I) couple of 1. Bulk electrolysis of 1, 2, or 3 at a potential of ca. -1.4 V vs E(Fc(+)/ Fc) in the presence of TFA yields H-2 with Faradaic yields close to 100%. A catalytic mechanism is proposed in which the pyridine moiety of a PN ligand acts as a pendant proton donor following opening of the chelate ring. Additional mechanisms may also operate, especially in the presence of high acid concentration where speciation changes.

Defects Engineering on Ceria and C-C Coupling Reactions Using [Au-11(PPh3)(7)I-3] Nanocluster: A Combined Experimental and Theoretical Study

Ligand protected atom-precise gold-based catalysts have been utilized in many essential chemical processes, but their mechanism and the fate of the catalyst during reaction are still unrevealed. Atom-precise cluster without ligands are thus highly desirable to maximize atom efficiency, but making these in solution phase is challenging. In this scenario, catalysts with dispersion on oxide support are highly desirable to understand the role of metal core during catalytic reaction. Here, we report the synthesis of Au-11(PPh3)(7)I-3 cluster that consists of an incomplete icosahedron core. During its impregnation process on CeO2 support, all of the ligands were removed from the kernel and the Au-11 kernel fits into the defects of ceria (embedded onto the oxygen vacancy of ceria (111) plane). This Au-11@CeO2 has high atom efficiency and catalytic activity for Ullmann-type C-C homocoupling reactions for electron rich substrates. Density functional theory calculations showed that hexagonal arrangements of Au-11 kernel on (111) plane of CeO2 is the most stable one. Theoretical calculations also proved that the atop gold atom has more favorable interaction with phenyl iodide than the second layer gold atoms of the Au-11@CeO2. This demonstrated that the present catalyst mimics the single-atom catalyst-like behavior in facilitating the coupling reactions.

Regioselective Synthesis of Chromones via Cyclocarbonylative Sonogashira Coupling Catalyzed by Highly Active Bridged-Bis(N-Heterocyclic Carbene)Palladium(II) Complexes

The one-pot regioselective and catalytic synthesis of bioactive chromones and flavones was achieved via phosphine-free cyclocarbonylative Sonogashira coupling reactions of 2-iodophenols with aryl alkynes, alkyl alkynes, and dialkynes. The reactions are catalyzed by new dibromidobis(NHC)palladium(II) complexes. The new bridged N,N’-substituted benzimidazolium salts (L1, L2, and L3) and their palladium complexes C1, C2, and C3 were designed, prepared, and fully characterized using different physical and spectroscopic techniques. The molecular structures of complexes C1 and C3 were determined by singlecrystal X-ray diffraction analysis. They showed a distorted square planar geometry, where the Pd(II) ion is bonded to the carbon atoms of two cis NHC carbene ligands and two cis bromido anions. These complexes displayed a high catalytic activity in cyclocarbonylative Sonogashira coupling reactions with low catalyst loadings. The regioselectivity of these reactions was controlled by using diethylamine as the base and DMF as the solvent.

Rapid Electrochemical Methane Functionalization Involves Pd-Pd Bonded Intermediates

High-valent Pd complexes are potent agents for the oxidative functionalization of inert C-H bonds, and it was previously shown that rapid electrocatalytic methane monofunctionalization could be achieved by electro-oxidation of Pd-II to a critical dinuclear Pd-III intermediate in concentrated or fuming sulfuric acid. However, the structure of this highly reactive, unisolable intermediate, as well as the structural basis for its mechanism of electrochemical formation, remained elusive. Herein, we use X-ray absorption and Raman spectroscopies to assemble a structural model of the potent methane-activating intermediate as a Pd-III dimer with a Pd-Pd bond and a 5-fold O atom coordination by H2SO4(x-2) ligands at each Pd center. We further use EPR spectroscopy to identify a mixed-valent M-M bonded Pd-2(II,III) species as a key intermediate during the Pd-II-to-Pd-III, oxidation. Combining EPR and electrochemical data, we quantify the free energy of Pd dimerization as <-4.5 kcal/mol for Pd-2(II,III) and <-9.1 kcal/mol for P-2(III). The structural and thermochemical data suggest that the aggregate effect of metal-metal and axial metal-ligand bond formation drives the critical Pd dimerization reaction in between electrochemical oxidation steps. This work establishes a structural basis for the facile electrochemical oxidation of Pd-II to a M-M bonded Pd-III dimer and provides a foundation for understanding its rapid methane functionalization reactivity.

Mechanistic Insights into Co and Fe Quaterpyridine-Based CO2 Reduction Catalysts: Metal-Ligand Orbital Interaction as the Key Driving Force for Distinct Pathways

Both [Co-II(qpy)(H2O)(2)](2+) and [Fe-II(qpy)(H2O)(2)](2+) (with qpy = 2,2′:6′,2 ”:6 ”,2”’-quaterpyridine) are efficient homogeneous electrocatalysts and photoelectrocatalysts for the reduction of CO2 to CO. The Co catalyst is more efficient in the electrochemical reduction, while the Fe catalyst is an excellent photoelectrocatalyst ( ACS Catal. 2018, 8, 3411-3417). This work uses density functional theory to shed light on the contrasting catalytic pathways. While both catalysts experience primarily ligand-based reductions, the second reduction in the Co catalyst is delocalized onto the metal via a metal-ligand bonding interaction, causing a spin transition and a distorted ligand framework. This orbital interaction explains the experimentally observed mild reduction potential and slow kinetics of the second reduction. The decreased hardness and doubly occupied d(z2)-orbital facilitate a sigma-bond with the CO2-pi* in an eta(1)-kappa C binding mode. CO2 binding is only possible after two reductions resulting in an EEC mechanism (E = electron transfer, C = chemical reaction), and the second protonation is rate-limiting. In contrast, the Fe catalyst maintains a Lewis acidic metal center throughout the reduction process because the metal orbitals do not strongly mix with the qpy-pi* orbitals. This allows binding of the activated CO2 in an eta(2)-binding mode. This interaction stabilizes the activated CO2 via a pi-type interaction of a Fe-t(2g) orbital and the CO2-pi* and a dative bond of the oxygen lone pair. This facilitates CO2 binding to a singly reduced catalyst resulting in an ECE mechanism. The barrier for CO2 addition and the second protonation are higher than those for the Co catalyst and rate-limiting.

Unsymmetrical Dinuclear Ru-II Complexes with Bridging Polydentate Nitrogen Ligands as Potential Water Oxidation Catalysts

Mononuclear Ru-II complex [RuCl(kappa N-3-tpm)(kappa N-2-bptz)]Cl, [1]Cl [tpm=tris(1- pyrazolyl)methane; bptz=3,6-di(2-pyridyl)-1,2,4,5-tetrazine], and dinuclear complexes [RuCl(kappa N-3-tpm)(mu-kappa N-2:kappa N-2-bptz)Ru(kappa N-2-bipy)(2)][PF6](3), [3][PF6](3), [RuCl(eta(6)-p-cymene)(mu-kappa N-2:kappa N-2-dpp)Ru(kappa N-2-bipy)(2)][PF6](2), [4][PF6](2), and [RuCl(eta(6)-p-cymene)(mu-kappa N-2:kappa N-2-dpp)Ru(kappa N-2-biqn)(2)][PF6](3), [5][PF6](3) [dpp=2,3-bis(2 ‘-pyridyl)-pyrazine; bipy=2,2 ‘-bipyridine; biqn=2,2 ‘-quinoline], incorporating both potentially catalytic and photosensitive subunits, were synthesized and characterized by means of elemental analysis, mass spectrometry, and spectroscopic methods. The molecular structures of the new compounds were also investigated and compared by means of DFT calculations. The absorption spectra of all the compounds are dominated by metal-to-ligand charge-transfer bands in the visible (which in most cases largely extend over the red portion of the spectrum) and ligand-centered bands in the UV region. The oxidation behavior is based on metal-centered Ru-II to Ru-III oxidation processes, which in phosphate buffer solution are followed by a catalytic water oxidation wave for [1]Cl and [3][PF6](3). For these compounds, the mechanism of water oxidation is proposed to consist in water nucleophilic attack, according to chemical experiments with Ce(IV) salts, so demonstrating for the first time that the bptz ligand can be profitably used to build ruthenium(II) complexes with catalytic properties. On the contrary, no catalytic process is observed for 4 and 5, most likely due to the high positive potential for Ru-II oxidation induced by the presence of the p-cymene moiety.

Electrochemical response of a Ru(II) benzothiazolyl-2-pyridinecarbothioamide pincer towards carbon dioxide and transfer hydrogenation of aryl ketones in air

A ruthenium(II) complex of 6-(4,7-dimethoxy-2-benzothiazolyl)-N-(2,5-dimethoxyphenyl)-2-pyridinecarbothioamide (pbcta), of the formula [Ru(pbcta)Cl-2(dmf)] (1, where DMF = dimethyl form-amide) was prepared from RuCl3 center dot xH(2)O and pbcta in DMF at reflux under argon atmosphere. The identity of 1 was confirmed from its elemental analysis, ESI MS, and a series of spectroscopic measurements. Voltammetric measurements on 1 in DMF and DFT studies on the structure optimized in the gas phase revealed predominantly ligand based electron transfer processes under argon. In the presence of a proton source, proton coupled electron transfer to the ligand occurs. Under a carbon dioxide atmosphere, voltammetric studies revealed that 1 is inactive for CO2 reduction, and the redox responses observed in the presence of the proton source and/or CO2 are ligand based leading to reactions with the coordinated pbcta. Transfer hydrogenation (TH) of aryl ketones was efficiently carried out in 2-propanol using 1 at reflux. TH of the aryl ketone substrates proceeded in air with almost quantitative conversions at 0.2-1.0 mol% catalyst. (C) 2020 Elsevier B.V. All rights reserved.

A combined experimental and theoretical rationalization of an unusual zinc(ii)-mediated conversion of 18-membered Schiff-base macrocycles to 18-membered imine-amine macrocycles with imidazolidine side rings: an investigation of their bio-relevant catalytic activities

The 2 : 2 condensation reaction of 2,6-diformyl-4-isopropyl phenol and N ‘-(2-aminoethyl)ethane-1,2-diamine leads to a macrocycle Schiff base ligand (H2L) with the N6O2 chromophore, which in the presence of ZnX2 transforms into a new [2+2] 18 membered macrocyclic system (H2L1) with an N4O2 chromophore and two exo-cyclic imidazolidine rings. The transformation of H2L to H2L1 in the presence of ZnX2 is unique and was confirmed by single crystal X-ray diffraction. The structural analysis reveals that the transformation generates complexes with a dinuclear Zn(ii) core connected to a ZnX3 moiety, leading to trinuclear species with the composition [Zn-3(L-1)(X)(5)](CH3OH)(H2O). The complexes (X = Cl, 1 and X = Br, 2) are also isostructural, where the central and terminal Zn atoms have different coordination geometries (trigonal-bipyramidal and tetrahedral, respectively). A probable mechanistic pathway involved in the conversion of the 18-membered imine-imine macrocycles to 18-membered imine-amine macroycles with imidazolidine excyclic rings has been established by combined experimental and theoretical investigations. Both these complexes (1 and 2) were exploited to check their phosphatase-like activity using the disodium salt of 4-nitrophenylphosphate (4-NPP) as a model substrate in a 97.5% (v/v) DMF-H2O mixture. The turnover numbers (k(cat)) of complexes 1 and 2 were calculated to be 17.905 and 14.235 s(-1), respectively. The probable mechanistic pathway has been explored via trapping the intermediate species of the catalytic cycle by ESI-MS study. On considering the efficiency of the catalyst in phospho-ester bond hydrolysis, both complexes were tested for their anticancer activities on MDA-MB-231 (human breast cancer) and HeLa (cervical cancer) cell lines, as revealed by in vitro MTT assays. The better cell killing properties of complex 1 were further evidenced with the help of cell migration inhibition studies.
