Aerobic visible-light induced intermol. S-N bond construction has been achieved without the addition of photosensitizer, metal, or base. With this strategy, 1,2,4-thiadiazoles I (R = Ph, 4-methoxyphenyl, thiophen-3-yl, etc.; R1 = 4-methoxyphenyl, 2,6-dimethylphenyl, thiophen-2-yl, etc.) can be obtained from thioamides R/R1C(S)NH2. 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.
