Abstract

Efficient conversion of aryl triflates into the corresponding phenols has been accomplished with Et4NOH. In contrast to other cleavage reactions, such functional groups as nitro, ketone, halogen, amide and sulfonamide groups were intact under the reaction conditions. This mild removal of the trifluoromethanesulfonyl group would serve a new protecting group of phenols.
