especially large-scale, fundamental reactions like estercondensations, are highly desirable for many reactions. Bulky diarylammonium pentafluorobenzenesulfonates and tosylates serve as extremely active dehydration catalysts for the estercondensation reaction of carboxylicacids with equimolaramounts of sterically demanding alcohols and acid-sensitive alcohols. Typically, the esterification reaction is performed

Open-air and solvent-free ester condensation catalyzed by sulfonic acids
Estercondensation is one among the most fundamental organic transformations, and more environmentally benign alternatives to current esterification processes are needed. Under solvent-free and drying agent-free conditions, catalytic amounts of sulfonic acids promote estercondensationbetween an equimolar mixture of carboxylicacids and alcohols. In particular, p-toluenesulfonic acid (TsOH) and 10-camphorsulfonic
