Electron Transfer Properties of Alkoxyl Radicals. A Time-Resolved Kinetic Study of the Reactions of the tert-Butoxyl, Cumuloxyl, and Benzyloxyl Radicals with Alkyl Ferrocenes

A time-resolved kinetic study on the reactions of the tert-butoxyl, cumyloxyl,and benzyloxyl radicals with alkylferrocenes has been carried out in MeCN solution. With all radicals, clear evidence for an electron transfer (ET) process has been obtained, and with the same ferrocene donor, the reactivity has been observed to increase in the order t-BuO.
