A selective oxidation of benzylic C(sp3)–H bonds to C(sp3)–O bonds catalyzed by copper complexes of quinoline–imine ligands was developed with peresters as oxidants under mild reaction conditions, which converted benzylic methylenes directly into benzylic alcohols and esters by means of direct C–H bond functionalization.

A tetrabutylammonium iodide catalyzed method has been developed for the one-pot synthesis of allylic and benzylic esters from -oxo carboxylic acids and alkenes/alkylbenzenes via decarboxylation and C-H bond activation. Various allylic and benzylic esters were obtained in good yield.
