Efficient photolytic C–H bond functionalization of alkylbenzene with hypervalent iodine(iii) reagent†
Abstract
A practical approach to radical C–H bond functionalization by the photolysis of a hypervalent iodine(III) reagent is presented. The photolysis of [bis(trifluoroacetoxy)iodo]benzene (PIFA) leads to the generation of trifluoroacetoxy radicals, which allows the smooth transformation of various alkylbenzenes to the corresponding benzyl ester compounds under mild reaction conditions.
