The condensation of 5-amino-4-phenyl-1,2,3-triazole (1) with chalcones 2a-e or 3-dimethylamino-propiophenone (4f) leads to the 6,7-dihydro-(1,2,3)-triazolo[1,5-a]pyrimidines 3a-f. The equilibrium of 3 and the tautomeric 4,7-dihydro-(1,2,3)-triazolo[1,5-a]pyrimidines 3′ is described.
5-氨基-4-苯基-1,2,3-三唑(1)与查耳酮2a-e或3-二甲基氨基-苯乙酮(4f)缩合生成6,7-二氢-(1,2,3 )-三唑并[1,5 - a ]嘧啶3a-f。描述了3和互变异构体4,7-二氢-(1,2,3)-三唑并[1,5- a ]嘧啶3'的平衡。

The scope of the title process has been studied, showing that anions 4â² having RÂ =Â H, (substituted) Ph and CO2Me react cleanly (and still satisfactorily in the case RÂ =Â Me), while with RÂ =Â COMe, COAr and CN extensive decomposition occurs. The experimental findings (rate constants, activation parameters) have been elucidated through PM3 calculations.
