Comprehensive Summary Visible light‐induced transformation of CO 2 and CS 2 into value‐added products has attracted worldwide attention because it mimics nature. In this context, although visible‐light‐induced direct synthesis of dithiocarbamates and carbamates employing SO 2 and CO 2 as a C1 source has been reported, all these reactions are limited to the preparation of S ‐alkyl mono‐dithiocarbamates and O ‐alkyl mono‐carbamates. Herein, we report a visible‐light photoredox‐catalyzed multicomponent reaction of diazosulfonium triflates with amines and CS 2 or CO 2 . Mechanistic studies indicate that the diazomethyl radicals might be generated as the key intermediates, thus providing a direction for the application of diazomethyl radicals with other radical acceptors.
