摘要：

Photolysis of (η5-C5H5)Ni(R)PPh3 (R = Me, Et) in air-free benzene leads to the production of the stable radical (η5-C5H5)Ni(PPh3)2. In the presence of free ligands, L (L = PPh3, P(p-FPh)3, P(p-MeOPh)3, P(n-Bu)3, P(OEt)3, P(OPh)3, P(OMe)3, dppe/2, bipy/2, C2Ph2 and HCCPh), photolysis of (η5-C5H5)Ni(R)PPh3 leads to the production of (η5-C5H5)Ni(L)2. The ESR spectra of several derivatives of the radical, (η5-C5H5)NiL2, have been analysed and the variation of the sp hybridization of the phosphorus donor atom determined. © 1990.
