摘要:The present paper describes the synthesis of four differently substituted dibenzoylmethanes, viz., 1(m-nitropheny1)-3-(p-chloropheny1)-, 1-(m-notropheny1)-3-(p-bromopheny1)-, 1,3-di(p-methoxypheny1) and 1-(p-ethoxypheny1)-3-pheny1 propane-1,3-diones and study of their coupling reactions with different diazotised sulphonamide bases. The resulting 2-sulphonamidobenzeneazo derivatives were subjected to biological assay in vitro against S. aureus and E. coli and some of these found to posses considerable activity.
