Abstract

The atom transfer radical cyclisation (ATRC) of non-activated alkyl bromides was realized under blue light irradiation in carbonate-buffered aqueous SDS solution using a catalytic system of CuBr2, Me6-TREN and ascorbic acid. The beneficial effect of SDS micelles can be accounted for by the activation of the C-Br bond as well as by the suppression of competitive reductive cyclisation.
