The kinetics and activation parameters for the series of 4-substituted (R) 1,2,4-triazoline-3,5-diones (R = Me, Et, But, CH2Ph, Ph, p-MeOC6H4, p-NO2C6H4, or N:CHPh) have been measured for the Diels–Alder reactions with diphenylbutadiene, anthracene, hexachlorocyclopentadiene, and bicyclo[2.2.1]heptadiene. The reactions have been studied in benzene, dioxan, and ethyl acetate. The results are more in
一系列4-取代的(R)1,2,4-三唑啉-3,5-二酮(R = Me,Et,Bu t,CH 2 Ph,Ph,p -MeOC 6 H 4的动力学和活化参数,p -NO 2 C 6 H 4或N:CHPh)已与二苯基丁二烯,蒽,六氯环戊二烯和双环[2.2.1]庚二烯进行了Diels-Alder反应。已经在苯,二恶烷和乙酸乙酯中研究了反应。结果更符合Diels-Alder反应的前沿反应性轨道模型,而不是标准的线性自由能方法。
