Abstract

Abstract As an example of the general problem posed in the title, the reduction of CF, Br, CFJ, C6F131, and CBFI7I by outer-sphere heterogeneous (glassy-carbon electrodes) and homogeneous (aromatic anion radicals) reagents is investigated, in aprotic solvents containing tetralkylammonium salts, by cyclic voltammetry and preparative-scale electrolysis. A RF* chemistry is thus triggered in all cases with the exception of CFIBr ...
