摘要：

The diiodo dimers [(η5-C5H5)M(NO)I2]2 (M = Mo, W) react with 10 equiv of PMe3to produce the new electron-rich nitrosyl complexes M(NO)(PMe3)4I, the other product being [(C5H5)PMe3]I. It has been shown that the formation of the tetrakis-(phosphine) complexes proceeds sequentially via the isolable intermediate species (η5-C5H5)M(NO)I2(PMe3) and [(η5-C5H5)M-(NO)I(PMe3)2]I. Treatment of the diiodo dimers with 4 equiv of PMe3in the presence of a reducing agent such as sodium amalgam affords excellent yields of the related complexes (η5-C5H5)M(NO)(PMe3)2(M = Mo, W), which also contain electron-rich transition-metal centers. The analytical and spectroscopic properties of all new complexes prepared are presented. © 1987, American Chemical Society. All rights reserved.
