不同取代的恶唑与4-苯基-1,2,4-三唑-3,5-二酮反应,通过恶唑开环,高产率地得到了N-苯基-5-酰基-Δ3- 1,2,4-三唑啉-1,2-二甲酰亚胺。通过单晶X射线分析确定了其中一种加合物的结构。
The reaction of various substituted oxazoles with 4-phenyl-1,2,4-triazole-3,5-dione gave anomalous cycloadducts, N-phenyl-5-acyl-Δ3-1,2,4-triazoline-1,2-dicarboximides in high yields through oxazole ring opening. The structure of one of the adducts was determined by a single-crystal X-ray analysis.
