In the present study we have reacted the five aryl diazonium salts prepared from nitro substituted anilines and amino substituted benzoic acids and coupled with Quinolin-8-ol and Active methylene group of pent-1,4-dione respectively. Synthesized compounds are then identified by FTIR Spectroscopical method.The final product, I to V formed has potential to use as azo dyes and asanintermediate in other synthetic procedures or transformations along with this they exhibits good biological activities.
