Abstract
The complex trans-[IrZ(CO)(PMePh2)2] (Z = Cl or Br) undergoes an oxidative addition reaction, at room temperature, at the sulfur—sulfur bond of diphenyl disulfide, (PhSSPh), phenyl benzenethiosulfonate, (PhSSO2Ph), and phenyl benzenesulfinylsulfonate, (PhS(O)SO2Ph). Diphenyl disulfone is unreactive at 75°C. Phenyl benzenethiosulfinate (PhSS(O)Ph) disproportionates in the reaction medium. The iridium(I) complex also inserts into the sulfur—sulfur bond of 1,2-dithiolene-1,1-dioxide, (S(O)2(CH2)3S). Thionyl chloride adds to square planar iridium(I) compounds to give iridium(III) complexes containing the chlorosulfinyl group (-S(O)Cl). The remaining sulfur—chlorine bond is reactive toward methanol producing the coordinated methoxy sulfinyl group.
