The reaction between sodium trifluoromethanesulfinate, which was prepared from trifluoromethyl bromide, with bromine in aqueous solution resulted in the formation of trifluoromethanesulfonyl bromide (CF 2 SO 2 Br). CF 3 SO 1 Br reacted with alkenes and alkyne to give the corresponding adducts with the loss of SO 2 in good yields, and with compounds containing active hydrogen to give brominated derivatives. A radical reaction mechanism was proposed and confirmed by EPR study.
