Abstract To study the mechanism of N-chlorination of secondary amines by chloramine-T, the kinetics of the reactions of some aromatic-substituted analogues of N- chlorobenzenesulfonamide with various secondary amines were determined. The importance of amine basicity and reactivity of the N [BOND] Cl bond of the N- chlorobenzenesulfonamide was also assessed. The results indicate that a mechanism ...
