A variety of N-acyl-N-(4-chlorophenyl)-4-nitrobenzenesulfonamides (1a-e) were synthesized in one pot from 4-chloroaniline under solvent-free conditions and have been developed as chemoselective N-acylation reagents. Selective protection of primary amines in the presence of secondary amines, acylation of aliphatic amines in the presence of aryl amines, and monofunctionalization of primary-secondary diamines as well as selective N-acylation of amino alcohols using these reagents are described. All of the acylation reactions were carried out in water as a green solvent. High stability and easy preparation of these acylating reagents are other advantages of this method.

The tighter ion pair effect and scale-up study in aminolysis of enolizable esters using potassium tert-butoxide (t-BuOK) under microwave irradiations is described. This method provides synthetic advantages in terms of reaction time, product yields, eco-friendly environment and scale-up feasibility over the conventional heating method.
