<br/><br/> 2-bromo-1-(5-methyl-1-(p-tolyl)-1H-1,2,3-triazol-4-yl) ethanone and 5- acetyl-4-methyl-2-(phenylamino)thiophene-3-carboxylate were used for the synthesis of several heterocyclic compounds as: 1,3,4-thiadiazoles, thiazoles, unsymmetericl azines, triazolo[3,4-a]pyrimidines, coumarines, 1,3,4-selenadi-azoles, [1,3,4] thiadiazolo [3,2-a]quinazolin-5-one, 1,3,4-thiadiazines, 3a,6a- dihydropyrrolo [3,4-c] pyrazolo-4,6(1H,5H)-dione, pyrazoles and pyrazolo[3,4- d]pyridazines. All the newly synthesized compounds were elucidated via elemental analysis, spectral data (IR, 1H NMR and MS) and alternative synthetic  routes whenever possible. The newly synthesized compounds were screen test against microorganism
