An efficient preparation of α-substituted acrylonitriles 6 based on the utilization of 4-cyano-3-ketothiolane enolate anion (3) as a synthetic equivalent to α-acrylonitrile anion (1) is described.

stoichiometric electron donor/acceptor is rare. Herein, we report such a process to access 2,3-difunctionalized pyridines from readily available N-aminopyridiniums (1) and activated alkenes (2) promoted by visible light. This procedure offered multi-substituted pyridines in satisfactory yields at room temperature with broad functional group tolerance. The reaction can be easily performed on a gram scale without
