Synthesis, Structure, and Reactivities of the (eta)1:(eta)6-(mu)2-Aryl Alkynyl Diruthenium Complex. X-Ray Structure of [Cp(PPh3)2Ru((eta)1:(eta)6-(mu)2-C=CC6H4Me-p)RuCp*]PF6 (Cp = (eta)5-C5H5, Cp* = (eta)5-C5Me5)

Palladium complexes efficiently catalyze the addition of O,O,S-triphenyl phosphorothioate to terminal alkynes to produce (Z)-1(diphenoxyphosphinyl)-2-(phenylthio)alkenes in high yields with high regio- and stereoselectivity.
