Trifluoromethanesulfonic anhydride, also known as triflic anhydride, is the chemical compound with the formula (CF 3 SO 2) 2 O. It is the acid anhydride derived from triflic acid . This compound is a strong electrophile , useful for introducing the triflyl group , CF 3 SO 2 .
Triflic acid, the short name for trifluoromethanesulfonic acid, TFMS, TFSA, HOTf or TfOH, is a sulfonic acid with the chemical formula CF 3 SO 3 H. It is one of the strongest known acids . Triflic acid is mainly used in research as a catalyst for esterification .
Triflyl group. In organic chemistry, the triflyl group (systematic name: trifluoromethanesulfonyl group) is a functional group with the formula R−SO 2 CF 3 and structure R−S(=O) 2 −CF 3.
A 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 extremely reactive in S N 2 reactions, they must be stored in conditions free of nucleophiles (such as water).
Bistriflimidic acid. The conjugate acid of bistriflimide, which is frequently referred to by the trivial name bistriflimidic acid (CAS: 82113-65-3), is a commercially available superacid.
Trifluoromethanesulfonyl azide is prepared by treating trifluoromethanesulfonic anhydride with sodium azide, traditionally in dichloromethane. [1] However, the use of dichloromethane is avoided since it can generate highly explosive azido-chloromethane and diazidomethane.
