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 <(CO)5MP(C6H5)2>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.
