Reactive intermediates from carbonylation of ruthenium(I) carbonyl carboxylates. Isolation, molecular structures and chemical properties of dinuclear unbridged ruthenium carbonyl trifluoroacetates
Abstract
Carboxylato-bridged Ru(I) carbonyl complexes are activated by CO towards both disproportionation and reaction with dihydrogen, through the intermediacy of the unbridged metal–metal bonded valence isomers (OC)5RuRu(CO)3- (OCOCR3)2 and [Ru(CO)4(OCOCR3)]2.
