Studies in Sulphonamides- Part VIII

1-Ary1-3-methypropane-1,3-diones, viz.,1-(4/Sup1 chloropheny1),1-4'-bromopheny1)-1-(4'-chloro-3'-methy1-pheny1)-and -bipheny1-3-methy1Propane-1,3-dions have been synthesised and coupled with different dinzotises sulphonamied, bases in presence of sodium acetate to furnish the respective 1-ary1-3- methy1-2(subsituted sulphonamidobe-nzeneazo propane-1,3-diones.All these azo compounds have been tested in vitro for their antibacterial properties against S. aureus and E. coli and majority of these are found active against S. aureus
