Photocatalytic hydrogen atom transfer is a very powerful strategy for the regioselective C(sp3)–H functionalization of organic molecules. Herein, we report on the unprecedented combination of decatungstate hydrogen atom transfer photocatalysis with the oxidative radical–polar crossover concept to access the direct net-oxidative C(sp3)–H heteroarylation. The present methodology demonstrates a high functional group

Tetrahydrofuran is a privileged structural moiety in many important organic compounds. In this work, we have developed a simple and mild catalytic oxidative amination of tetrahydrofuran mediated by visible-light catalysis. The C(sp3)-H bond of tetrahydrofuran was activated using molecular oxygen as a benign oxidant. Besides, a variety of azoles could be tolerated, providing a green route for N-substituted

A versatile and scalable flow reactor for electrophotocatalysis is presented. The reactor can simultaneously exploit photons and electrons. The efficacy of this reactor was demonstrated in a novel electrophotocatalytic heteroarylation of C(sp3)−H bonds.
