A visible-light-driven three-component reaction of isocyanides, diselenides and trimethylsilyl azide (TMSN3) was carried out to synthesize selenotetrazoles under mild conditions. When the solvent system and additives were adjusted, this reaction also efficiently afforded selenocarbamates. The protocol features broad substrate scope and excellent functional-group tolerance, and a plausible reaction mechanism is proposed.
