Dissociative Adsorption and Hydrogenolysis of Ethane over Clean and Ni-Covered
The hydrogenolysis of ethane has been investigated on clean and Ni-covered Pt( 1 1 1) at reactant partial pressures between 0.5 and 4 Torr of ethane and between 80 and 270 Torr of hydrogen and for surface temperatures from 550 to 640 K. On clean Pt( 1 1 1) the hydrogenolysis reaction proceeds with an activation energy of 36.6 kcal/mol and reaction orders in C2H6 and H2 pressures of 1 and -1.8, ...
متن کاملSelective, 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 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.
