Abstract
New alkyl and phenyl complexes [Ru(CO)2L2ClR](L = PMe2Ph or PMePh2: R = Me, Et, or Ph) have been prepared by reaction of the all-trans- or all-cis-isomers of [Ru(CO)2L2Cl2] with HgR2 or SnMe4: the cis-isomers of [Ru(CO)2L2Cl2] do not react with these reagents. Mechanisms for the reactions, involving initial dissociation of a carbonyl ligand, are proposed on the basis of information about their stereochemistry and kinetics, and studies of halide-exchange reactions of all-trans-[Ru(CO)2(PMe2Ph)2Cl2] with bromide and iodtde ion. In the case of reactions between [Ru(CO)(PMe2Ph)3Cl2] and HgR2, in which complexes [Ru(CO)(PMe2Ph)3ClR] are formed as intermediates, the transfer of alkyl or phsnyl ligand between mercury and ruthenium has been found to be reversible.Keywords
