A powerful free radical Markovnikov hydrofluorination of unactivated alkenes is mediated by Fe(III)/NaBH4 using Selectfluor reagent as a source of fluorine. In contrast to the traditional radical hydrofluorination of alkenes, the Fe(III)/NaBH4-mediated reaction is conducted under exceptionally mild reaction conditions, tolerates various functional groups, and even runs open to the air and with water as a cosolvent.
