摘要：

The compound (Ph2PMe2Si)(3)CH I reacted (i) with [Mo(CO)(6)] to give cis-[Mo(CO)(4){(Ph2PMe2Si)(3)CH)] 1 in which two phosphine groups are co-ordinated to molybdenum and one is free, and (ii) with LiBu in the presence of N,N,N',N'-tetramethylethane-1,2-diamine (tmen) to give [Li(tmen)(2)][C(SiMe2PPh2)(3)] 2, which contains discrete planar carbanions and no Li-P co-ordination. The crystal structures of compounds I and 2 have been determined and 1 has been characterised spectroscopically.
