anti-Markovnikov Iodofluorination of Alkenes.

The fluorination of alkenes with electrophilic N-F type reagents usually occurs through a Markovnikov-type addition, and the anti-Markovnikov-type addition may require the use of a transition metal catalyst or an expensive catalyst. Herein we describe a convenient anti-Markovnikov iodofluorination of alkenes with Selectfluor/ Bu NI. A wide substrate scope and good functional group tolerance were observed.
