英文摘要 | In addition to pyridines, α-chloroformylarylhydrazine hydrochloride 1 can also react with some N-heterocyclic compounds. The cycloaddition of 1 with isoquinoline was achieved to obtain 3. The production of 4, 5, 6 given by cycloaddition of 1 with pyridazine was dependent on the reaction condition. Some heterocyclic compounds bearing an X-C=N (X:S,N) group on the ring can react with 1 to gain the derivatives of 2,4-dihydro-1,2,4-triazol-3-one. 7, 8, 9 and 10 were given by reaction of 1 with 1,3,5-triazine, 1,4,5,6-tetrahydropyrimidine, 1, 3-thiazole and 2-amino- 1, 3-thiazole, respectively. The reactions for 2-amino-1,3,4-thiadiazole and 3-amino-1,2,4-triazole had the same product 11. |
