Depending on the substitution on the hydrazine moiety, thermolysis of 3-phenyl-1,2,4-oxadiazol-5-ylhydrazines (1)–(5) gives variable amounts of 1-amino-Δ2-1,2,4-triazolin-5-ones (13) or (17), Δ2- or Δ3-1,2,4-triazolin-5-ones (12), (18), or (19), and the s-triazine (20). A possible mechanism accounting for the products and the effects is discussed. A diradical intermediate and a hydrogen transfer from
根据在肼基部分的取代,3-苯基-1,2,4-恶二唑-5- ylhydrazines热解(1) - (5)给出了不同量的1-氨基- Δ的2 -1,2,4-三唑啉-5-酮(13)或(17),Δ 2 -或Δ 3 -1,2,4-三唑啉-5-酮(12),(18)或(19),并且š嗪( 20)。讨论了一种可能的解释产品及其效果的机制。根据过氧化苯甲酰对反应的影响以及肼(1)–(4)催化加氢的行为,提出了双自由基中间体和氢从反应介质中的转移。
