Abstract

{Kinetic and activation parameter data for the reactions of cct-Ru(H)(2)(CO)(2)(PPh(3))(2) (1) (cct = cis, cis, trans) in THF with thiols, CO and PPh(3) to give cct-RuH(SR)(CO)(2)(PPh(3))(2), Ru(CO)(3)(PPh(3))(2) and Ru(CO)(2)(PPh(3))(2), respectively, reveal a common, rate-determining step, the initial dissociation of H-2 from 1; the activated complex probably resembles the corresponding Ru(eta(2)-H-2) species. Reaction of Ru(H)(2)(dppm)(2) (2) (as a cis/trans mixture
