Abstract

Gold(I) alkoxides, Au(OR)L (L = PPh3, PCy3; R = CH(CF3)2, CH2CF3, Ph) smoothly abstract a hydrogen from transition metal hydrides (MH = CoH(CO)4, MoHCp(CO)3, WHCp(CO)3, MnH(CO)5, WHCp(CO)2(PPh3)) to give corresponding dinuclear complexes LAu-M with liberation of equimolar amount of ROH. Similar reactions of gold(III) alkoxides, cis-AuMe2-(OR)L also give dinuclear intermediates LMe2Au-M, from which preferential reductive elimination of ethane takes place when M is more electron withdrawing.
