摘要

在 3,6-二苯基-1,2,4,5-四嗪与 2-氨基-4-芳基噁唑的无溶剂反应过程中，发现了一种新的转化，从而生成了 2,5,7-三芳基[1,2,4]三唑并[1,5-a]嘧啶。单晶 X 射线衍射数据也证实了产物的结构。提出了这一反应的可能机理。

A New Approach to the Synthesis of [1,2,4]Triazolo[1,5-a]pyrimidines by Reaction of 1,2,4,5-Tetrazines with 2-Aminoxazoles

A new transformation of 3,6-diphenyl-1,2,4,5-tetrazine was discovered during the solvent-free reaction with 2-amino-4-aryloxazoles, leading to the formation of 2,5,7-triaryl[1,2,4]triazolo[1,5-a]pyrimidines. Stucture of products was also confirmed by single crystal X-ray diffraction data. A possible mechanism for this reaction was proposed.
