The acylation of primary and secondary amines by 5-phenyltetrazol-2-ylacetyl chloride leads to the corresponding tetrazolylacetamides irrespective of the nature of the substituent in the structure of the amine. 相似文献

A method for the preparation of new 3-nitro-1,2,4-triazole derivatives has been suggested based on modification of the N-hydroxymethyl group by nitration and nucleophilic substitution reactions. Thermal stability of 3-nitro-1,2,4-triazole N-nitroxy- and N-azidomethyl derivatives, as well as of dinitrates, 5,5′-dinitro-2,2 ′-bisnitroxymethyl-2 H,2′H-3,3 ′-bi(1,2,4-triazole) and -(nitromethylene)bis(1,2,4-triazole), has been studied. 相似文献

It was shown using 5-phenyl-2-tetrazolylacetic acid ethyl ester as an example that aminolysis is a competitive method of synthesizing primary amides. The efficiency of aminolysis by primary amines is linked to the basicity of the initial amine. Highly basic amines display more high reactivity independent of the spatial structure of the substituent. Reaction of the investigated ester with secondary amines occurs ambiguously. 相似文献
