  2. Bis(trifluoromethanesulfonyl)aniline - Wikipedia

    en.wikipedia.org/wiki/Bis(trifluoromethanesulfo...

    Bis(trifluoromethanesulfonyl)aniline is the organic compound with the formula C 6 H 5 N(SO 2 CF 3) 2. [1] It is a white solid. The compound is used to install the triflyl group (SO 2 CF 3). Its behavior is akin to that of triflic anhydride, but milder.

  3. Triflyl group - Wikipedia

    en.wikipedia.org/wiki/Triflyl_group

    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.

  4. Triflate - Wikipedia

    en.wikipedia.org/wiki/Triflate

    For example, n-butyl triflate can be written as CH 3 CH 2 CH 2 CH 2 OTf. The corresponding triflate anion, CF 3 SO − 3, is an extremely stable polyatomic ion; this comes from the fact that triflic acid (CF 3 SO 3 H) is a superacid; i.e. it is more acidic than pure sulfuric acid, already one of the strongest acids known.

  8. Sulfonamide - Wikipedia

    en.wikipedia.org/wiki/Sulfonamide

    Bis(trifluoromethanesulfonyl)aniline is a source of the triflyl (CF 3 SO + 2) group. The disulfonimides are of the type R−S(=O) 2 −N(H)−S(=O) 2 −R' with two sulfonyl groups flanking an amine. [10] As with sulfinamides, this class of compounds is used as catalysts in enantioselective synthesis. [10] [11] [12]
