Reaction of the coordinatively unsaturated alkenyl complexes Ru(CO)Cl(RC=CHR′)(PPh3)2 with CO gives two types of compounds, the dicarbonyl complexes Ru(CO)2Cl(RC=CHR′)(PPh3)2 (R = H, R′ = H, Ph, tBu, SiMe3, CO2Me or CO2Et and R = R′ = CO2Me) and the η2-acyl complexes Ru(CO)Cl(η2-O=CCR=CHR′)(PPh3)2 (R = R′ = Me, Et and Ph). The reaction of sodium proprionate with the Ru(CO)Cl(η2-O=CCMe=CHMe)(PPh3)2 complex yields a new product containing both η2-alkeneacyl and η2-propionate ligands. The structures of the new complexes were established from their IR and NMR spectra. © 1991.
