Synthesis and Reactions of Five-Coordinate Mono- and Binuclear Thiocarbonyl-Alkenyl and Thioacyl Complexes of Ruthenium(II)

Abstract

The reactions of [RuHCl(CS)(PPh3)3] with R 1C≡CR2 (R1 = R2 = H, Ph, CO2Me; R1 = H, R2 = C6H 4Me-4; R1 = C≡CPh, R2 = Ph) lead to the five- or six-coordinate (R1 = R2 = CO2Me) σ-alkenyl complexes [Ru(CR1=CHR2)Cl(CS)(PPh 3)2], the stilbenyl derivative b
