Photoexcited sulfenylation of C(sp3)–H bonds in amides using thiosulfonates

A photoexcited sulfenylation of C(sp3)–H bonds in amides is developed for the synthesis of sulfenyl amides using thiosulfonates as a sulfur source. In the presence of easily available and inexpensive Na2-eosin Y, TBHP and K2CO3, various sulfenyl amides can be obtained under the irradiation of blue light at room temperature.
