Abstract

Two procedures for the conversion of coordinated CS₂ into CS ligands are described involving the intermediacy of either η²-carbonsulphide-telluride or hydridodithiomethoxycarbonyl complexes. The CS₂ ligand in OsCl(NO)(CS₂)(PPh₃)₂ is readily methylated to provide cationic dithiomethoxycarbonyl-containing complexes, which upon reduction with sodium hydrotelluride and sodium tetrahydroborate give OsX(NO)(CS)(PPh₃)₂ (X = Cl, I) and OsH₂ (CS₂Me)(NO)(PPh₃)₂, respectively. The latter reacts with electrophilic reagents (HCl, HI, I₂) to give OsX(NO)(CS)(PPh₃)₂, the halide of which is labile and is easily extracted by silver salts, allowing coordination of neutral ligands and providing the cations [Os(NO)(CS)(PPh₃)₂L]⁺ (L = CO, PPh₃). OsH₂(CS₂Me)(NO)(PPh₃)₂ and OsI(NO)(CS)(PPh₃)₂ react with an excess of I₂ to give the ionic product [OsI₂(NO)(CS)(PPh₃)₂]⁺I₃^-.
