A Facile Synthesis of a Wide Variety of Cationic Ruthenium Hydrido-Arene Complexes of binap (=1,1′-Binaphthalene-2,2′-diylbis(diphenylphosphane)) and MeObiphep (=6,6′-Dimethoxybiphenyl-2,2′-diylbis(diphenylphosphane))
摘要:
A straightforward high-yield synthetic route to the cationic hydrido-arene complexes [RuH(eta(6)-arene)(binap or MeO-biphep)](CF3SO3), with a variety of arenes containing both donor and acceptor substituents, is described. C-13-NMR Data for these complexes are reported. Several of these Ru-complexes have been used as transfer-hydrogenation catalysts in the reduction of acetophenone.
