Abstract
Abstract Activation of small inorganic molecules (H2, N2, O2, CO, NO, CO2, SO2, CS2) by the complexes of transition metal ions like Rh(I), Ir(I), Pt(O) and Ru(II) have gained considerable interest during the last decade.1–8 Because of the similarity of CO2 and CS2 molecules with COS, one would expect COS to form complexes with the transition metal ions analogous to those of CO2 and CS2. In addition, COS being susceptible to decomposition into CO and S, could also form carbonyl complexes. Until now, the only reaction of COS that has been successfully carried out is with [Pt(PPh3)3] which resulted in the formation of [Pt(COS)(PPh3)2] and [Pt2S(CO) (PPh3)3]. 8,9 It will, therefore, be interesting to study further the reactions of COS with the complexes of transition metal ions. The results of a preliminary study of such reactions with [Rh(PPh3)3Cl] and [Pt(PPh3)3] are reported in this communication.
