Selective, nickel-catalyzed hydrogenolysis of aryl ethers.
Selective hydrogenolysis of the aromatic carbon-oxygen (C-O) bonds in aryl ethers is an unsolved synthetic problem important for the generation of fuels and chemical feedstocks from biomass and for the liquefaction of coal. Currently, the hydrogenolysis of aromatic C-O bonds requires heterogeneous catalysts that operate at high temperature and pressure and lead to a mixture of products from com...
متن کاملBoryl-assisted hydrogenolysis of a nickel-methyl bond.
A stable nickel(II) methyl complex containing a diphosphino-boryl (PBP) pincer ligand is described. Mechanistic studies on the hydrogenolysis of the Ni-Me bond suggest a metal ligand cooperation mechanism that involves the intermediacy of a σ-B-H Ni(0) species that further undergoes B-H oxidative addition to form a Ni(II) hydride complex.
متن کاملFormation of α-[KSiH3] by hydrogenolysis of potassium triphenylsilyl.
Hydrogenation of easily accessible potassium triphenylsilyl [K(Me6TREN)SiPh3] gave the hydrogen storage material α-[KSiH3] in high yields by an unusual hydrogenolytic cleavage of silicon-phenyl bonds.
متن کاملFormal palladium-catalyzed asymmetric hydrogenolysis of racemic N-sulfonyloxaziridines.
Highly enantioselective palladium-catalyzed formal hydrogenolysis of racemic N-sulfonyloxaziridines has been realized, providing a novel access to sultams with up to 99% ee. Preliminary mechanistic insights revealed that the reaction proceeded through a N-O bond cleavage, dehydration, and the sequential asymmetric hydrogenation.
متن کاملChemoselective hydrogenolysis of tetrahydrofurfuryl alcohol to 1,5-pentanediol.
Direct conversion of tetrahydrofurfuryl alcohol, which is one of the biomass-derived chemicals, to 1,5-pentanediol was realized by chemoselective hydrogenolysis catalyzed by Rh/SiO(2) modified with ReO(x) species, and this reaction route gave higher yield than the conventional multi-step method.
