solvent-tuned electrochemical protocol for the selectivetransferhydrogenation of imidazopyridines using carbazates as hydrogendonors has been developed. This electrosynthesis strategy provides a more sustainable and greener way to access partially saturated N-heterocycles by avoiding traditionally employed transition metal catalysts and high-pressure hydrogen. Remarkably, the method is scalable and applicable

A novel, simple, and practical visible-light-mediated intramolecular α-C(sp3)–H imination of tertiaryaliphaticamines containing β-O-aryl oximes leading to N-heterocycles has been developed. The reaction was performed well at rt with tolerance of some functional groups. Importantly, the selective C–H functionalization did not require added catalyst, oxidant, additive, acid, and base; visible light
