Electrochemical studies of metal carbonyl compounds

This article reviews our studies over some twenty years on the oxidative redox chemistry of Ise carbonyl derivatives of the group 6 and 7 transition metals. The necessity of coupling electrochemical and spectroscopic techniques is emphasized. Probably in all cases, the first oxidative step is a one-electron process and the subsequent chemistry of the system depends upon the stability and reactivity of 17e product. Isomerization is a common phenomenon, but when this is not possible disproportionation is often observed. (C) 1997 Elsevier Science S.A.
