摘要：

Reaction of diphenyl(ferrocenyl)phosphine (1), tri(ferrocenyl)phosphine (2) and (t)butyl(diferrocenyl)phosphine (3) with one equivalent of 2,3-dichloro-4,5-dicyano-1,4-benzoquinone (DDQ) yields FcPPh2 (.) DDQ (4), Fc(3)P (.) 9 DDQ (5) and Fc(2)P(t)Bu (.) DDQ (6), respectively. Infrared, UV-Vis and ESR spectra of 4-6 are consistent with formation of DDQ(.-) Mossbauer spectroscopy, however, reveals that 4-6 all contain low spin Fell suggesting that the radical cation is ligand centered rather than iron centered.
