Synthesis, Characterization and Antimicrobial Activity of Metal Chelates of 5-(4-N, N-Diethylamino sulfonyl phenyl azo)-8-hydorxy quinoline

4-N,N-Diethylamino sulfonyl phenyl amine was synthesized by diazotization and coupled with 8-hydroxyquinoline. The resultant 5-(4-N,N-diethylamino sulfonyl phenyl azo)-8-hydorxy quinoline (DSAQ) was characterized by elemental analysis and spectral studies. The transition metal chelates viz. Cu2
