Nucleophilic attack on a ligand as a pre-requisite for ligand replacement. Kinetics and mechanism of the replacement of PMe2Ph by P(OMe)3 in [Ru(S2CH)(PMe2Ph)3{P(OMe)3}]+
Abstract
Kinetic data reveal that nucleophilic attack of added PMe2Ph on the dithioformato carbon atom of the title complex catalyses the substitution of PMe2Ph by P(OMe)3to give [Ru(S2CH)(PMe2Ph)2{P(OMe)3}2]+; the structure of one of the intermediates is inferred from the isolation of [Ru{S2C(H)PMe2Ph}(PMe2Ph)2{P(OMe)2Ph}]+.
