The installation of azoles via C-H/N-H cross-coupling is significantly underdeveloped, particularly in benzylic C-H azolation due to the requirement for external chemical oxidants and the challenge in controlling the site- and chemo-selectivity. Herein, a late-stage azolation of benzylic C-H bonds enabled by electrooxidation is described, which proceeds in an undivided cell under mild, catalyst- and

A visible light mediated highly selective benzylic C–H bond functionalization for intermolecular C–N and C–O bond formation is reported. This cross-dehydrogenative coupling reaction demonstrates a straightforward protocol for incorporating the heteroaromatics to the benzylic position. Benzylic oxidation of various alkyl aryls to corresponding carbonyl compounds has also been reported.
