procedure for the preparation of allylic trifluoromethanesulfones with high regioselectivity from aromatic allylicalcohols/esters and NaSO2CF3 under transition-metal-free conditions is described. A wide range of functional groups were tolerated. This is the first example to realize different types of allylicalcohols, including primary, secondary, and tertiary allylicalcohols, all of which transferred to
