ABSTRACT
About more than 85% yields of some aryl sulphonamides were synthesised by sodium acetate catalysed ultrasonication promoted condensation of aryl amines and benzene sulfonyl chlorides in room temperature. The synthesised sulfonamides were analysed with their physical constants, micro analysis and spectral techniques. The antioxidant potential of these sulfonamides were assessed by DPPH radical scavenging activity measurement using L-ascorbic acid as a standard. Antimicrobial activities of these sulfonamides have been assessed by disc diffusion method against their antimicrobial stains. Most of the sulfonamides shows antimicrobial activity. Many of the hydroxy and methoxy substituted sulfonamides showed significant antioxidant activity.
