Hydrosilylation of Carbonyl Compounds with Hydrosilyliron Complexes Catalyzed by Cationic Silyleneiron Complexes
摘要:
A hydride abstraction from the hydrosilyliron complexes Cp(OC)(2)FeSiR2H (Cp = eta(5)-C5H5, R = p-tolyl (la), Me (1b)) in CD3CN afforded cationic silyleneiron complexes [Cp(OC)(2)Fe=SiR2(NCCD3)][13(Ar-f)(4)] (Ar-f = 3,5-bis(trifluoromethyl)phenyl, R = p-tolyl (2a), Me (2b)). The cationic silylene complexes 2 catalyzed hydrosilylation of aldehydes and ketones with 1 to give the corresponding alkoxysilyliron complexes 3-5 in moderate to high yield.
