Addition compounds of dichlorodioxomolybdenum(VI) with sulfoxides.: Molecular structure of [MoO2Cl2(Me2SO)2]

MoO2Cl2L2 (L = dimethyl sulfoxide (Me2SO), deuterated dimethyl sulfoxide (Me2SO-d(6)), di-n-buthyl sulfoxide (Bu2SO), tetramethylene sulfoxide (C4H8SO), dibenzyl sulfoxide (Bz(2)SO), diphenyl sulfoxide (Ph2SO), di-p-tolyl sulfoxide (p-Tol(2)SO), di-p-chloro-phenyl sulfoxide (p-Cl-Ph2SO) and methyl phenyl sulfoxide (MePhSO)) have been prepared by reacting a solution of MoO2Cl2(H2O)(2) in diethyl ether with the respective ligand. The molecular structure of MoO2Cl2(Me2SO)(2) has been established by X-ray diffraction analysis. The ability of representative complexes to work as oxotransfer catalysts has been tested.
