1-Phenylsulfonylbenzotriazole: A novel and convenient reagent for the preparation of benzenesulfonamides and aryl benzenesulfonates

Readily available 1-phenylsulfonylbenzotriazole smoothly converts various aliphatic and aromatic amines and phenols into the corresponding benzenesulfonamides and benzenesulfonates in good yields.

Heterocycles in Organic Synthesis. Part 42. Preparation of Azides, Phthalimides, and Sulphonamides from Primary Amines

N-Alkyl and N-benzyl substituents are displaced from 2,4,6-triphenylpyridinium cations by nucleophilic azide, phthalimide, succinimide, and sulphonamide anions.This enables the conversion of primary alkyl- and benzylamines into azides, and primary (with potential for inversion or labelling) and secondary amines.
