摘要：

Wilkinson's catalyst, RhCl(PPh3)(3) (1), undergoes a one-electron oxidation at a sufficiently low, potential (E-1/2 = +0.035 V vs Fc) to allow a facile electron-transfer reaction with mild oxidants such as the ferrocenium ion. The Rh(II) cation If decomposes rapidly to the very reactive intermediate 2, which over longer reaction times gives rise to the three-coordinate complex [Rh(PPh3)(3)](+) (4).
