Abstract

The most commonly used synthetic methods to manipulate sulfonamides involve the nucleophilic attack by ammonia, or primary or secondary amines, with sulfonyl chlorides in the presence of a base. Although this method is efficient, it requires the availability of sulfonyl chlorides, some of which are hard to prepare and difficult to store or handle. Side reactions are also possible due to the presence of base or liberated nucleophilic chloride, particularly under harsh ...
