Abstract

Quantum yields for C-C bond scission are at least 50 times larger in radical cations of methoxybicumenes (1^.+) generated by quenching of the p-tetrachlorobenzoquinone (TCBQ) excited state (a process that results in triplet solvent-separated ion pairs) than in those obtained by the irradiation of [TCBQ ⋯ (1)] charge-transfer complexes (a reaction that yields singlet contact ion pairs).
