Abstract

{Sequential treatment Of M(CO)6 (M = MO, W) in THF with Cp(phi)Li (Cp(phi) = eta5-C5Ph4H) and Diazald (N-methyl-N-nitroso-p-toluenesulfonamide) affords good yields of Cp(phi)M(NO)(CO)2 which convert to Cp(phi)M(NO)Cl2 upon treatment with PCl5 in Et2O. Dialkyl compounds of the type Cp#M(NO)R2 (R = CH2SiMe3, CH2Ph) are readily preparable from these dichloro precursors by straight forward metathesis reactions. Finally, molybdenum dinitrosyl complexes of the type Cp(phi)Mo(NO)2X (X = Cl, Ph) are obtained when Cp(phi)Mo(NO) (CO)2 is reacted with [NO] [PF6] in CH2Cl2 and the resulting [Cp(chi)Mo(NO)2]PF6 intermediate salt is treated in situ with a source of X-. All new complexes have been characterized by conventional means, and an X-ray crystallographic analysis of CP(phi)W(NO)(CH2SiMe3)2 has been performed. Crystal data for Cp(phi)W(NO)(CH2SiMe3)2: triclinic, space group P1BAR
