摘要

二苯甲醇与取代苯的反应有助于生成三芳基甲烷衍生物,三芳基甲烷是各种功能材料和生物相关物质的重要骨架。该反应是在微波环境下进行的。在环己烷中,微波辐射下的反应比常规加热下的反应更快。同样,当使用超过0.8等量的氯化铁时,观察到加速。值得注意的是,当氯化铁(III)和芳烃结合时,反应溶液的温度上升到40℃。认为氯化铁(III)与二苯甲醇或芳烃配位形成了一种化学物质。

Effect of Microwave Irradiation on Friedel-Crafts Diphenylmethylation of Arenes
The reaction between diphenylmethanols and substituted benzenes is useful to yield triarylmethane derivatives which are important skeletons in various functional materials and biologically relevant substances. The Reactions were carried out under microwave irradiation as environmentally-friendly method. In cyclohexane, the reaction was accelerated under microwave irradiation as compared to under conventional heating. Also, when more than 0.8 equivalents of iron(III) chloride were used, the acceleration was observed. Notably, when iron(III) chloride and arenes were combined, the temperature of the reaction solution rose to 40°C. It is considered that a chemical species was formed upon coordination of iron(III) chloride to the diphenylmethanols or arenes.
