Hydrogenation of alpha,beta-Unsaturated Carbonyl Compounds over Covalently Heterogenized Ru(II) Diphosphine Complexes on AlPO4-Sepiolite Supports

In this work, the covalent immobilization of two ruthenium(II) complexes, i.e., [(RuCl)-Cl-II (bpea){(S)(-)(BINAP)}](BF4), 1, and [(RuCl)-Cl-II(bpea)(DPPE)](BF4), 2, where BINAP = 2,2′-bis(diphenylphosphino)-1,1′-binaphthyl and DPPE = 1,2-bis(diphenylphosphino)ethane, have been obtained (AlPO4-Sepiolite@1 and AlPO4-Sepiolite@2) by using a N-tridentate ligand N,N-bis-(2-pyridylmethyl)ethylamine (bpea), linked to an amorphous AlPO4-Sepiolite (20/80) inorganic support. This AlPO4-sepiolite support is able to immobilize the double amount of ruthenium complex (1.65%) than the amorphous AlPO4 (0.89%). Both heterogenized complexes have been assessed as catalysts in the liquid phase hydrogenation of several substrates with carbonyl and/or olefinic double bonds using methanol as solvent, attaining good catalytic activity and high enantioselectivity (99%). The highest Turn Over Number (TON) value (748.6) was obtained over the [(RuCl)-Cl-II (bpea)(DPPE)](BF4)2 catalyst, although the [(RuCl)-Cl-II(bpea){(S)(-)(BINAP)}](BF4) 1 exhibits better reusability. In fact, the [(RuCl)-Cl-II(bpea){(S)(-)(BINAP)}](BF4) immobilized on AlPO4-Sepiolite maintained the activity throughout 14 successive runs. Furthermore, some findings on hydrogenation mechanisms of the alpha,beta-unsaturated carbonyl compounds over Ru catalysts have been also obtained.

A new Co-based metal-organic coordination polymer as a catalyst in chemical fixation of CO2

A 1D MOF {[Co(XN)(HCOO)(2)(H2O)(2)]}(n) (1) was harvested by solvothermal method with organic ligand XN (4′-(4-pyridine)4,2′:2′,4 ”-terpyridine), and structurally characterized by single-crystal X-ray diffraction, PXRD and TGA. Structural determination demonstrates that compound 1 owns zigzag shape framework through the infinite connection of Co2+ ion and XN ligand. Moreover, it can resist 240 degrees C and various acid/ alkali solutions, presenting good thermostability and pH stability. Catalytic performance indicates that compound 1 can efficiently catalyze the CO2 cycloaddition with styrene oxide at 80 degrees C and 0.1 MPa with the addition of 5% mol TBAB for 12 h. Especially, compound 1 can keep stable framework and almost unchanged catalytic activity after five catalytic recyclings. (C) 2020 Elsevier Ltd. All rights reserved.

Iron Catalyzed Isomerization of alpha-Alkyl Styrenes to Access Trisubstituted Alkenes

Main observation and conclusion Stereoselective isomerization of alpha-alkyl styrenes is accomplished using a new iron catalyst supported by phosphine-pyridine-oxazoline (PPO) ligand. The protocol provides an atom-efficient and operationally simple approach to trisubstituted alkenes in high yields with excellent regio- and stereoselectivities under mild conditions. The results of deuterium-labelling and radical trap experiments are consistent with an iron-hydride pathway involving reversible alkene insertion and beta-H elimination.

Cyanosilylation of carbonyl compounds catalyzed by half-sandwich (eta(6)-p-cymene) Ruthenium(II) complexes bearing heterocyclic hydrazone derivatives

A new class of half-sandwich (eta(6)-p-cymene) ruthenium(II) complexes supported by heterocyclic hydrazone derivatives of general formula [Ru(eta(6)-p-cymene)(Cl)(L)] where L represents N’-((1H-pyrrol-2-yl)methylene) furan-2-carbohydrazide (L-1), N’-((1H-pyrrol-2-yl)methylene)thiophene-2-carbohydrazide (L-2) or N’-((1H-pyrrol-2-yemethylene)isonicotinohydrazide (L-3) were synthesized. Both ligand precursors and complexes were characterized by elemental and spectral analysis (IR, UV-Vis, NMR and mass spectrometry). The molecular structures of all Ru complexes [Ru(eta(6) -p-cymene)(Cl)(L)] were determined by single-crystal X-ray diffraction as threelegged piano-stool. The Ru(II) complexes were used as catalysts for the cyanosilylation of aldehydes (aliphatic, aromatic, alpha,beta-unsaturated and heterocyclic aldehydes) with trimethylsilyl cyanide (TMSCN). All reactions were performed at room temperature and catalytic conditions as solvents, catalyst and catalyst loading were experimentally optimized. Using 0.5 mol% of Ru catalyst 3 in Et2O it was possible to prepare cyanosilylethers in good-to-excellent isolated yields.

Catalytic access to carbocation intermediates via nitrenoid transfer leading to allylic lactams

Carbocation intermediacy is postulated in numerous organic transformations and provides the foundation for retrosynthetic logics in chemical synthesis. Although a number of catalytic approaches are designed to generate transient carbocations under mild conditions, there is room for improvement in the context of selectivity control and synthetic utility. Here we present an approach that enables catalytic access to carbocation intermediates via metal-nitrenoid transfer into alkenes, which subsequently allows a regiocontrolled elimination reaction. Customized catalysts are capable of bypassing competing pathways of the reactive intermediates to furnish valuable allylic lactams with excellent regioselectivity. Mechanistic investigations suggest that the ligand plays a critical role as an internal base in the selectivity-determining proton transfer process. This protocol is broadly applicable for preparing both five- and the more challenging four-membered allylamides. The virtue of this platform is further demonstrated by achieving the enantioselective construction of gamma-lactams.

Rational Design of a Zn-II MOF with Multiple Functional Sites for Highly Efficient Fixation of CO2 under Mild Conditions: Combined Experimental and Theoretical Investigation

The development of efficient heterogeneous catalysts suitable for carbon capture and utilization (CCU) under mild conditions is a promising step towards mitigating the growing concentration of CO2 in the atmosphere. Herein, we report the construction of a hydrogen-bonded 3D framework, {[Zn(hfipbba)(MA)].3 DMF}(n) (hfipbba=4,4 ‘-(hexaflouroisopropylene)bis(benzoic acid)) (HbMOF1) utilizing Zn-II center, a partially fluorinated, long-chain dicarboxylate ligand (hfipbba), and an amine-rich melamine (MA) co-ligand. Interestingly, the framework possesses two types of 1D channels decorated with CO2-philic (-NH2 and -CF3) groups that promote the highly selective CO2 adsorption by the framework, which was supported by computational simulations. Further, the synergistic involvement of both Lewis acidic and basic sites exposed in the confined 1D channels along with high thermal and chemical stability rendered HbMOF1 a good heterogeneous catalyst for the highly efficient fixation of CO2 in a reaction with terminal/internal epoxides at mild conditions (RT and 1 bar CO2). Moreover, in-depth theoretical studies were carried out using periodic DFT to obtain the relative energies for each stage involved in the catalytic reaction and an insight mechanistic details of the reaction is presented. Overall, this work represents a rare demonstration of rational design of a porous Zn-II MOF incorporating multiple functional sites suitable for highly efficient fixation of CO2 with terminal/internal epoxides at mild conditions supported by comprehensive theoretical studies.

Unusual magnetism in CuxCo3-xO4 nanoparticles

In Cu-doped Co3O4 nanoparticles (CuxCo3-xO4; 0 <= x <= 0.5) Cu occupies both octahedral and tetrahedral sites with a 2+ oxidation state. As the Cu doping increases, we observe changes in the crystal structure corresponding to a Jahn-Teller distortion of the Cu2+ sites. To mediate charge balance with Cu2+ entering the octahedral sites, a hole forms in the O 2p orbitals bonded to the Cu2+(O-h). Cu2+(T-d) is noninteracting and disrupts the existing antiferromagnetic interactions between the Co2+(T-d) ions, while Cu2+(O-h) exhibits a ferromagnetic response as a result of a hybrid form of exchange occurring between Cu2+(O-h) and Co2+(T-d). Emergence of the 3d(9) ligand hole is directly responsible for the origin of ferromagnetic Cu in the octahedral sites and this results in the unusual magnetism in CuxCo3-xO4. Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 3105-95-1.

Preparation, characterization and photocatalytic performance of titania particles encapsulated in hollow silica shells as an efficient photocatalyst for redox-combined stereoselective synthesis of l-pipecolinic acid from l-lysine

Hollow core-shell particles of a titania core and a silica shell, the latter of which was highly porous, water-swollen and not directly connected to the former, were synthesized by a multistep process including carbon and silica coatings followed by calcination of the carbon-layer combustion. The core-shell particles suspended in aqueous solutions of l-lysine showed improved stereoselectivity in photocatalytic redox-combined synthesis of l-pipecolinic acid (l-PCA), maintaining l-lysine conversion and PCA selectivity, compared with that by bare titania particles, presumably due to the acidic microenvironment of the titania core to control the position of oxidation by positive holes as the first step of the redox-combined process. Modification of the silica layers to acidify them was also beneficial for improvement of optical purity of the product, PCA.
