英文摘要 | Reactions of aniline with 3-arylsydnone-4-carbohydroximic acid chlorides (1) gave the desired substitution products 5. 3-Arylsydnone-4-carboxamide phenylhydrazones (7) were obtained unexpectedly by the reaction of carbohydroximic acid chlorides 1 with phenylhydrazine in suitable conditions. Compounds 7 could react with both aromatic and aliphatic aldehydes in the presence of acid catalyst to give 3-aryl-4-(1¢-phenyl-5¢-substituted-1¢,2¢,4¢-triazol-3¢-yl)sydnones (11). |
