In organic chemistry, the triflyl group (systematic name: trifluoromethanesulfonyl group) is a functional group with the formula R−SO2CF3 and structure R−S(=O)2−CF3. The triflyl group is often represented by –Tf. The related triflate group (trifluoromethanesulfonate) has the formula R−OSO2CF3, and is represented by –OTf. WebA triflate group is an excellent leaving group used in certain organic reactions such as nucleophilic substitution, Suzuki couplings and Heck reactions. Since alkyl triflates are …
