with sodium derivatives of pentane-2,4-dione, malonodinitrile, Meldrum acid, acetoacetic, cyanoacetic and malonic esters have been shown to give the respective substituted derivatives. Azinyl-ylidene tautomerism has been found to be characteristic of these compounds, the latter existing mainly in the ylidene form. The acid hydrolysis of pentane-2, 5-dione and cyanoacetic and malonic esters derivatives
2-溴-7-甲基-5-氧代-5H-1,3,4-噻二唑并[3,2-a]嘧啶与戊烷-2,4-二酮、丙二腈、Meldrum酸、乙酰乙酸、氰乙酸酯和丙二酸酯已显示出各自的取代衍生物。已经发现氮杂-亚基互变异构是这些化合物的特征,后者主要以亚基形式存在。已经研究了戊烷-2、5-二酮和氰基乙酸酯和丙二酸酯衍生物的酸水解。
