Practical fluorothiolation and difluorothiolation of alkenes using pyridine-HF and N-thiosuccinimides

Abstract

We have developed highly efficient fluorothiolation and difluorothiolation of alkenes under simple and mild conditions. Our fluorothiolation reagents are the commercially available Olah's reagent (Py-HF) and readily available N-thiosuccinimides. This transition metal-free system offers good chemical yields for a wide range of alkene substrates with excellent regioselectivity and good functional group tolerance.
