As a development of our previous work, we performed a kinetic study of the oxidative cyclization reaction of some 2,4-diaryl-substituted aldehyde thiosemicarbazones 1a-n induced by ferric chloride and by cupric perchlorate. The results of cyclization of 1a-n were compared to those of the corresponding 2-methyl derivatives. The kinetic data were analyzed by means of the Hammett's equation.
作为我们先前工作的发展,我们对氯化铁和高氯酸铜诱导的一些2,4-二芳基取代的醛硫代半碳唑酮1a-n的氧化环化反应进行了动力学研究。将1a-n的环化结果与相应的2-甲基衍生物的环化结果进行了比较。通过哈米特方程分析动力学数据。
