The unsaturated alkenyl complexes Ru(CO)Cl(RCCHR′)(PPh3)2 react with CS2 and CO2 to give Ru(CO)Cl(S2CRCCHR′)(PPh3)2 and Ru(CO)Cl(O2CRCCHR′)(PPh3)2 complexes, respectively. The products are hexacoordinated-ruthenium(II) complexes containing alkenedithiocarboxylate or alkenecarboxylate ligands η2-coordinated to metal. In these reactions CS2 and CO2 insert into rutheniumalkenyl bonds to form new chelated ligands. The structures of products and the nature of the alkenedithiocarboxylate and alkenecarboxylate ligands have been established from spectroscopic data (IR, 1H and 31P NMR). © 1991.
