Abstract
Reactions of aniline with 3-arylsydnone-4-carbohydroximic acid chlorides (1 ) gave the desired substitution products 5. 3-Arylsydnone-4-carboxamide phe nylhydrazones (7) were obtained unexpectedly by the reaction of carbohydrox imic acid chlorides 1 with phenylhydrazine in suitable conditions. Compound s 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'-triazo l-3'-yl)sydnones (11).
