Abstract

Electrochemical oxidation of Rh2(TMB) 4 2+ (TMB = 2,5-diisocyano-2,5-dimethylhexane) in the presence of 1,4-cyclohexadiene produces benzene and two protons. It is probable that a key step in the reaction is hydrogen-atom transfer from 1,4-cyclohexadiene to electrochemically generated Rh2(TMB) 4 3+ . The H-atom abstraction apparently is facilitated by the presence of a dσ* hole in the Rh 2 3+ 2 complex.
