What are the different types of sulfonamide synthesis?

For clear presentation, the syntheses of sulfonamide have been divided into two categories: (i) transition metal-free synthesis and (ii) transition metal-catalyzed synthesis of sulfonamide, which were then, subdivided according to their reaction types. 2.1. Transition metal-free synthesis of sulfonamide

How to synthesis aryl sulfonamide?

Scheme 3. Synthesis of aryl sulfonamide via chlorosulfonylation of aryl boronic acid. In 2017, Bode et al. reported the synthesis of pyridyl-sulfonamide by the reaction of the aryl sulfonyl chloride with 2-amino-6-bromopyridine in presence of pyridine as a base in refluxing acetonitrile for 24 h [ 28 ].
