| Резюме: | In this paper we prepared 4-nitrocenamic acid and cenamic acid (1,2) by reaction of one mole of (4-nitrobanzaldehyde and benzaldehyde) in the acetic hydrate potassium acetate as a base, then comes the reaction of number (1) compound to saturate double bond in brome to produce saturated acid (2,3- dibromo-3-(4-nitrophenyl) propionic acid (3) , and then the reaction of (2,3) compounds with thio semicarbazide by using conc was done . Sulpharic acid to obtain substituted thiodiazole (4,9) compounds and then reaction of compound (2) with semicarbazide to produce substituted oxadiazole (5) and then react substituted thiadaiazole (4,9) with sodium nitrate in presence of conc. hydrochloric acid to product 2-chloro-5-substitude -1,3,4-thiadiazole (6,10)..The compounds were identified by physical and spectral methods. |
