A dibenz[a,c]phenazine-supported N-heterocyclic carbene and its rhodium and iridium complexes

A new polycyclic N-heterocyclic carbene featuring a fused dibenz[a,c]phenazine moiety was generated in situ from the corresponding tetrafluoroborate salt. The synthesis and NMR data of its corresponding precursors, its sulfur adduct and dimer are reported

Zinc Hydride-Catalyzed Hydrofuntionalization of Ketones

Three new dimeric bis-guanidinate zinc(II) alkyl, halide, and hydride complexes [LZnEt]2 (1), [LZnI]2 (2) and [LZnH]2 (3) were prepared. Compound 3 was successfully employed for the hydrosilylation and hydroboration of a vast number of ketones. The catalytic performance of 3 in the hydroboration of acetophenone exhibits a turnover frequency, reaching up to 5800 h-1, outperforming that of reported zinc hydride catalysts. Notably, both intra- and intermolecular chemoselective hydrosilylation and hydroboration reactions have been investigated.

An isolable iron(ii) bis(supersilyl) complex as an effective catalyst for reduction reactions

An isolable 14-electron iron bis(supersilyl) complex, Fe[Si(SiMe3)3]2(THF)2, was successfully synthesized from the reaction of FeBr2 with K[Si(SiMe3)3] and its structure was unambiguously determined by single-crystal X-ray diffraction analysis. The complex is coordinatively unsaturated and exhibits high catalytic activity toward the hydrosilylation of carbonyl compounds and the reductive silylation of dinitrogen.

Efficient hydrosilylation of carbonyl compounds with the simple amide catalyst [Fe{N(SiMe3)2}2]

Keep it simple: A variety of ketones and two aldehydes underwent efficient hydrosilylation under mild conditions in the presence of the title complex (see scheme; R,R′=H, alkyl, aryl). In some cases, a catalyst loading of just 0.01-0.03 mol % was sufficie

Hydrosilylation of ketone and imine over poly-N-heterocyclic carbene particles

N-Heterocyclic carbene (NHC)-catalyzed ketone/imine hydrosilylation, silane alcohol condensation and asymmetric ketone hydrosilylation reactions were demonstrated for the first time over solid, main-chain poly-NHC particles. The stable and robust poly-NHC

HYDROSILYLATION

The present invention relates to a process for converting a substrate to a product comprising exposing the substrate to a hydrosilane in the presence of a carbene catalyst.

Designing the "Search pathway" in the development of a new class of highly efficient stereoselective hydrosilylation catalysts

A highly efficient class of N-heterocyclic carbene-based catalysts for the asymmetric hydrosilylation of prochiral ketones was discussed. The potential pitfalls associated with the nonlinearity in the behavior of an enantioselective catalyst in response to the variations of key reaction parameters were also described. The modular design of a new catalyst is based essentially on a single assembly step of its structural and functional subunits. It was observed that the direct coupling of oxazolines and N-heterocyclic carbenes leads to chelating C,N ancillary ligands for asymmetric catalysis that combines both an 'anchor' unit and a stereodirecting element.

Synthesis of novel axially chiral Rh-NHC complexes derived from BINAM and application in the enantioselective hydrosilylation of methyl ketones

Novel axially chiral Rh N-heterocyclic carbene complexes were prepared from axially dissymmetric 1,1′-binaphthalenyl-2,2′-diamine and applied in the Rh-catalyzed enantioselective hydrosilylation of methyl ketones. The corresponding sec-alcohols can be obtained in high yields with good to excellent ee.
