Aerobic visible-light induced intermolecular S?N bond construction has been achieved without the addition of photosensitizer, metal, or base. With this strategy, 1,2,4-thiadiazoles can be obtained from thioamides. Preliminary mechanistic investigation suggested that the excited state of thioamides undergoes a single-electron-transfer (SET) process to afford thioamidyl radicals, which can be further transformed into a 1,2,4-thiadiazole through desulfurization and oxidative cyclization. The reaction has good functional group tolerance and represents a green method for the construction of S?N bonds.

The sulfur-carbon electrode, used as a cathode, appears to be an excellent source of nucleophiles which are good sulfuration reagents towards alkenes not substituted by leaving groups.However, the electrochemical reactions are often complex.It should be w
