The diphenylphosphane complexes (CO)5MP(C6H5)2H (M=Cr,Mo,W) (Ia-Ic) react with sulfonyl chlorides, RSO2Cl, (R=CH3, p-CH3C6H4) in diethyl ether via the non-isolable sulfinylphosphinito-P complexes (CO)5M (IIa-IIc) to give the homogeneous anhydrides, the diphodoxane complexes 2O (IIIa-IIIc) and the sulfinylsulfolanes R(O)SS(O)2R.The composition and structures of complexes III result from the IR, 31P NMR and mass spectra.The crystal structure of IIIa has been determined IIIa crystalliyes in the space group Cc.Two nearly octahedrally arranged (CO)5CrP(C6H5)2 moieties are joined by an unsymmetrical oxygen-bridge in the all-trans position, the bond angle P(1)-OP(2) being 145 deg.
