A visible-light-induced, catalyst-free radical cross-coupling cyclization of diselenide or disulfides with N-allylbromodifluoroacetamides was developed. This developed protocol exhibited good functional group tolerance and afforded a variety of 4-thio- and 4-seleno-substituted 3,3-difluoro-γ-lactams I [R = c-Bu, Ph, 2-BrC6H4CH2, etc.; R1 = H, Me, Cl; X = S, Se] in moderate to good yields. Based on control experiments, a plausible radical-radical cross-coupling pathway was proposed. In the part of experimental materials, we found many familiar compounds, such as 1,2-Diphenyldisulfane(cas: 882-33-7SDS of cas: 882-33-7)
1,2-Diphenyldisulfane(cas: 882-33-7) belongs to ethers. Ethers lack the hydroxyl groups of alcohols. Without the strongly polarized O―H bond, ether molecules cannot engage in hydrogen bonding with each other. SDS of cas: 882-33-7
