Indol-2-ylidene (IdY): Ambiphilic N-Heterocyclic Carbene Derived from Indole

The synthesis of ambiphilic N-heterocyclic carbene ligand, indol-2-ylidene (IdY, A), is described. A series of indolenium precursors (2 a-f) were prepared on a gram scale in good yields. Trapping experiments with elemental selenium, [RhCl(cod)](2) and CuCl provided the expected carbene adducts. Further computational and spectroscopic studies supported the ambiphilicity of IdY, which lies between cyclic (alkyl)(amino)carbenes (CAAC-5) and cyclic (amino)(aryl)carbene (CAArC). The copper complexes (6) show high percent buried volume (% V-bur = 58.1) and allow for carboboration of terminal alkynes within 30 minutes in a demonstration of synthetic utility with good yields and high regioselectivity.

From carbones to carbenes and ylides in the coordination sphere of iridium

The carbodiphosphorane-based iridium pincer complex (2) is demonstrated to rearrange in chlorinated organic solvents under cleavage of a P-C-bond to give a chelating phosphine ylide ligand. A detailed mechanistic investigation reveals that these types of donor groups are prone for P-C-bond cleavage in the coordination sphere of transition metal hydrido complexes. Finally, complex 2 is demonstrated to be an efficient hydrogen-borrowing catalyst.

Functional polyesters via the regioselective ring-opening copolymerizations of norbornene anhydride with epichlorohydrin

The highly regioselective ring-opening copolymerizations of 5-norbornene-2,3-dicarboxylic anhydride (NA) and epoxide monomers have been successfully achieved using Cr-III catalyst bearing tetradentate imine-thioetherbridged bis(phenolate) ligand in combination with bis(triphenylphosphine)iminium chloride. The cis/trans regioselectivity of resulting polyesters can be tailored simply by controlling the feed ratio and the structure of monomer. Specifically, the polyesters produced by the copolymerization of NA and epichlorohydrin offer a robust platform for the post-modification. Thus, the ring-strained C=C double bonds in the norbornene units promote the azide-alkene 1,3-dipolar cycloaddition to functionalize the resulting polyesters depending on targets.

A new 3D luminescent Ba-organic framework with high open metal sites: CO2 fixation, luminescence sensing, and dye sorption

A new 3D luminescent Ba-organic framework {[Ba3L2(NMP)(2)(H2O)(2)]center dot 2NMP center dot H2O}(n) (1) was first synthesized based on Ba(II) and a triangular-shaped bridging rigid ligand, namely 1,3,5-tris(4-carboxyphenly)benzene (H3L), via solvothermal reaction (NMP = N-methyl pyrrolidone), thereby forming a stabilized network including a one-dimensional (1D) infinite rod-like helical metal chain. 1 may be explored as a recyclable heterogeneous catalyst for the efficient fixation of CO2 to form serviceable cyclic carbonate since 1D channels remain decorated with abundant open metal sites (OMSs), and the catalytic efficiency of 1 was up to 98% for 1-bromo-2,3-propylene oxide. Simultaneously, the luminescence sensing shows that 1 has excellent response and sensitivity towards pollutants such as Fe3+, Cr2O72-, CrO42-, and [Fe(CN)(6)](3-) ions. Moreover, 1 exhibits the particularly selective sorption towards the Congo red (CR) dye. Consequently, this study may provide a facile synthetic route for the construction of multi-functional Ba-MOF materials.

Multireference Description of Nickel-Aryl Homolytic Bond Dissociation Processes in Photoredox Catalysis

Multireference electronic structure calculations consistent with known experimental data have elucidated a novel mechanism for photo-triggered Ni(II)-C homolytic bond dissociation in Ni 2,2′-bipyridine (bpy) photoredox catalysts. Previously, a thermally assisted dissociation from the lowest energy triplet ligand field excited state was proposed and supported by density functional theory (DFT) calculations that reveal a barrier of similar to 30 kcal mol(-1). In contrast, multireference ab initio calculations suggest that this process is disfavored, with barrier heights of similar to 70 kcal mol(-1), and highlight important ligand noninnocent and multiconfigurational contributions to excited state relaxation and bond dissociation processes that are not captured with DFT. In the multireference description, photo-triggered Ni(II)-C homolytic bond dissociation occurs via initial population of a singlet Ni(II)-to-bpy metal-to-ligand charge transfer ((MLCT)-M-1) excited state, followed by intersystem crossing and aryl-to-Ni(III) charge transfer, overall a formal two-electron transfer process driven by a single photon. This results in repulsive triplet excited states from which spontaneous homolytic bond dissociation can occur, effectively competing with relaxation to the lowest energy nondissociative triplet Ni(II) ligand field excited state. These findings guide important electronic structure considerations for the experimental and computational elucidation of the mechanisms of ground and excited state cross-coupling catalysis mediated by Ni heteroaromatic complexes.

Nickel-Catalyzed Vinylidene Insertions into O-H Bonds

A (pybox)Ni catalyst (where pybox = pyridine-bis(oxazoline)) promotes the reductive cyclization of beta-hydroxy 1,1-dichloroalkenes to form 2,3-dihydrofurans. The substrates for this reaction are conveniently prepared by an aldol addition, followed by one-carbon homologation. Chiral substrates are accessible in highly enantioenriched form, allowing for the synthesis of stereochemically complex 2,3,4-trisubstituted products. Mechanistic studies support a vinylidene O-H insertion rather than a C-O cross-coupling pathway.

The homoleptic bis(beta-quinolylenolate) zinc catalysts for the ring-opening polymerization of epsilon-caprolactone: Kinetics and mechanism

A series of bis(beta-quinolylenolate) zinc complexes (L2Zn) 1-5 (L = [(2-C9H6N)-CH= C(R)-O-], R = tBu (1), Ph (2), o-tolyl (3), p-tolyl (4), p-OMePh (5)), have been structurally characterized and used as initiators in the ring-opening polymerization (ROP) of epsilon-caprolactone (epsilon-CL). The molecular structures of 3 and 4 were defined by X-ray diffriaction analyses, showing a distorted-tetrahedral geometry around the zinc center. All complexes are stable in air and high temperature, and they efficiently catalyzed the ROP of epsilon-CL with high conversions in a controlled manner. Kinetic studies showed that polymerization reaction catalyzed by 1-5 proceeded with first-order dependence on the monomer and their catalytic activity is correlated with the substituents on the Ar moieties of the ligand. Complex 3 displayed the higher activity than others, might be due to its stronger electron-donating nature of the ortho-Me group on the aryl ring (Ar) of the enamino framework than that of orther sites, however, complex 2 without substituent on the Ar group exhibited poor activity in the polymerization reaction. The resultant PCL was a mixture of linear BnO- and MeO-capped structures. (c) 2020 Elsevier B.V. All rights reserved.

An Anthracene-Based Metal-Organic Framework for Selective Photo-Reduction of Carbon Dioxide to Formic Acid Coupled with Water Oxidation

A Zr-based metal-organic framework has been synthesized and employed as a catalyst for photochemical carbon dioxide reduction coupled with water oxidation. The catalyst shows significant carbon dioxide reduction property with concomitant water oxidation. The catalyst has broad visible light as well as UV light absorption property, which is further confirmed from electronic absorption spectroscopy. Formic acid was the only reduced product from carbon dioxide with a turn-over frequency (TOF) of 0.69 h(-1) in addition to oxygen, which was produced with a TOF of 0.54 h(-1). No external photosensitizer is used and the ligand itself acts as the light harvester. The efficient and selective photochemical carbon dioxide reduction to formic acid with concomitant water oxidation using Zr-based MOF as catalyst is thus demonstrated here.

Homogeneously supported PtGa NPs on nitrogen-doped mesoporous carbon as an enhanced ORR electro-catalyst

Platinum (Pt) nanoparticle catalysts show excellent performance for oxygen reduction reaction (ORR), but the high cost of Pt directly limits the commercialization of Pt-based catalysts. Supported PtGa alloy nanoparticles (NPs) with modified surface property and reactivity through ligand, strain and/or ensemble effects are considered as promising inexpensive low-Pt candidates. In this article, we report a PtGa nanoparticles with a size of 3.8 +/- 0.4 nm anchored on nitrogen-doped mesoporous carbon (PtGa@NMC) for an efficient ORR electrocatalyst in alkaline electrolytes. The half-wave potential (E-1/2) values of PtGa@NMC (0.92 V vs RHE) positively shift similar to 30 mV compared to commercial Pt/C in 1 M KOH solution. And it has outstanding long-term durability by the result of accelerated durability tests (ADTs) and chronoamperometry (CA). Considering high performance and excellent stability, PtGa@NMC presents the possibility of replacing contemporary Pt-based catalysts. (C) 2020 Elsevier B.V. All rights reserved.

Pd/Cu-Free Cobalt-Catalyzed Suzuki and Heck Using Green Bio-Magnetic Hybrid and DFT-Based Theoretical Study

Several highly efficient and magnetically recyclable cobalt catalytic systems were prepared using magnetic chitosan and some safe and available organic compounds (Co-ligand@MNPs/Ch). The structure of these nanocomposites was confirmed by various physicochemical techniques such as FT-IR, XRD, TGA, VSM, TEM, SEM, CHNS and ICP-OES. These nano composites exhibit remarkable catalytic efficiency for Suzuki and Heck cross-coupling reactions in mild and green reaction conditions. The facile accessibility of starting materials, possible performance in air and eco-friendly conditions are merits of our catalysts. In addition, to describe and go insight to role and effect of ligands present in these catalysts, electrostatic interactions, density functional theory (DFT) model in molecular method were employed.
