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.
