Oxidation addition and other reactions of rhodium, iridium, and platinum complexes with carbon disulphide, ethyl dithiochloroformate, and acids

Abstract

The interactions of various substances which can undergo oxidative addition reactions with complexes of rhodium, iridium, and platinum have been studied and the new compounds characterised by i.r. and n.m.r. spectroscopy. The reactions investigated are the following : (a) CS₂ with RhX(PPh₃)₃(X = Me or Ph), RhH(CO)(PPh₃)₃, RhHCl₂(PEtPh₂)₃, Rhl₂Me(PPh₃)₂, IrH(CO)(PPh₃)₂; (b) CICSSEt with trans-RhCl(CO)-(PPh₃)₂, trans-RhCl(CO)[P(C₆H₄OMe)₃]₂, RhCl(PPh₃)₃, trans-IrCl(CO)(PPh₃)₂, and Pt(PPh₃)₃; (c)(CF₃)₂CS with IrH(CO)(PPh₃)₃; (d) C₆H₄(NH₂)SH with RhCl(PPh₃)₃, trans-RhCl(CO)(PPh₃)₂,Rh(CO)₂(acac), and [Rh(CO)₂Cl]₂; (e) Ph₂PSSH with RhCl(PPh₃)₃; and (f) RCO₂H with RhCl(PPh₃)₃ and IrH(CO)(PPh₃)₃.
