2,2,2-Trifluoroethanesulfonyl chloride tresyl

Reaction of surface hydroxyl groups with 2,2,2-trifluoroethanesulfonyl chloride (tresyl chloride) yields sulfonate esters which in a subsequent step can be reacted with amino- or mercapto-modihed biomolecules for covalent immobilization... 

A simple method for the activation of hydroxyl group carrying supports such as agarose, cellulose, diol-silica, glycophase-glass or hydroxyalkyl methacrylate copolymer with 2,2,2-trifluoroethanesulfonyl chloride (tresyl chloride) was introduced by Nilsson and Mosbach [108] ... 

Alkyl N-tresylarylsulfonimides can be obtained by the reaction of (2) with tresyl chloride (2,2,2-trifluoroethanesulfonyl chloride). ...
