Abstract

The use of N3SO2CF3 as an amination reagent and FeCl2 as a chloride source enables an efficient aminochlorination reaction of stryenes . The operationally simple procedure offers mild reaction conditions, good functional group compatibility, and high regioselectivity. Aminobromination using FeBr2 and a one-pot aminoazidation of styrenes are also realized.
