The synthesis of the potential bridging ligand (C6H5)2PCH2CH2Si(CH3)2C5H4 (3) is described.The ferrocene (6) derived from 3 has been found to form macrocyclic complexes with metal fragments NiCl2, NiBr2, and Co2(CO)6.Although monomeric, bimetallic products might have been expected based upon the reduced steric demands of ligand 3 relative to an analogous ligand, (C6H5)2PCH2Si(CH3)2C5H4 (1), it appears that the increased flexibility in 3 is the overriding factor leading to a preference for inter- rather than intramolecular coordination of the second phosphine function in 6.

The difunctional ligand (C6H5)2PCH2CH2Si(CH3)2 Li+ (1) is readily prepared in three steps via photolytic addition of diphenylphosphine to vinyldimethylchlorosilane, followed by reaction with lithium cyclopentadienide and deprotonation.Ligand 1 is of value in the construction of molecules containing pairs of different transition metals indirectly linked but not metal-metal bonded.
