The reaction of RhH(PPh3)4 with carbonyl sulfide affords trans-mercaptocarbonylbis(triphenylphosphine)rhodium(I), Rh(SH)(CO)(PPh3)2, in high yield. The product has been characterized by infrared, 1H, and 31P{1H} NMR spectroscopy and by an X-ray structure determination. A pathway to the formation of the compound is proposed that involves η2 coordination of the COS molecule to the metal center, with subsequent hydride transfer to the sulfur atom and C—S bond cleavage.
