6 Reaction with arylsulphonyl chloride
Benzenesulphonyl chloride (C6H5SO2Cl), which is also known as
Hinsberg’s reagent, reacts with primary and secondary amines to
form sulphonamides (a) The reaction of benzenesulphonyl chloride with primary amine
yields N-ethylbenzenesulphonyl amide The hydrogen attached to nitrogen in sulphonamide is strongly
acidic due to the presence of strong electron withdrawing sulphonyl
group
