Abstract

Treatment of 1-trimethylsilyloxy-1-cyclohexene (1a) in the presence of a catalytic amount of the acidic dihydrogen complex [RuCl (η2-H2)(dppe) 2] OTf (4a)[dppe= 1, 2-bis (diphenylphosphino) ethane, OTf= OSO2CF3](10 mol.%) under 1 atm of H2 in anhydrous ClCD2CD2Cl at 50° C for 8 h afforded cyclohexanone (3a) and Me3SiH in quantitative NMR yields. Silyl enol ethers such as 1-triethylsilyloxy-1-cyclohexene (1b), 1-t- ...
