Generation and trapping of benzyl radicals from benzyl iodides by cobaloximemediated iodine atom abstractions

Abstract

Ethylcobaloxime has been demonstrated to function as a convenient source of ethyl radicals on white light photolysis in ethanol. The ethyl radicals so generated take part in iodine abstractions with benzyl iodides giving benzyl radicals which may be trapped with 2,2,6,6-tetramethylpiperidinyloxyl (TEMPO) or lepidinium camphor-10-sulfonate.
