Triarylmethanes, which are valuable structures in materials, sensing and pharmaceuticals, have been synthesized starting from methyl phenyl sulfone as an inexpensive and readily available template. The three aryl groups were installed through two sequential palladium‐catalyzed CH arylation reactions, followed by an arylative desulfonation. This method provides a new synthetic approach to multisubstituted
三芳基甲烷是材料,传感和药物中的重要结构,已从甲基苯基砜作为廉价且易于获得的模板开始合成。三个芳基是通过两个连续的钯催化的安装在C ħ芳基化反应,接着是脱磺arylative。该方法使用易于获得的卤代芳烃和芳基硼酸为多取代的三芳基甲烷提供了一种新的合成方法,对于制备未开发的基于三芳基甲烷的材料和药物也很有价值。
