Method for synthesizing triarylmethane derivative and triarylmethane derivative obtained by method

The invention discloses a method for synthesizing a triarylmethane derivative. The triarylmethane derivative is synthesized through a one-pot reaction of various substituted salicylaldehyde, aromaticboric acid and aromatic hydrocarbon by taking ferric trichloride as a catalyst. The three different aryl groups are introduced from salicylaldehyde, arylboronic acid and aromatic hydrocarbon which arelow in price and easy to obtain in one step, the reaction has very high chemical selectivity, and a triarylmethane derivative with completely asymmetric groups is provided. The method has the advantages of simple operation, short reaction time, cheap and easily available catalyst, low production cost, less pollution, simple post-treatment, and very high yield of the reaction. 本发明公开了一种合成三芳基甲烷衍生物的方法，它是以三氯化铁为催化剂，由各种取代水杨醛、芳香硼酸和芳烃"一锅"反应合成得到。这三种不同的芳基是由价格低廉且容易获得的水杨醛、芳基硼酸和芳烃一步引入的，该反应具有很高的化学选择性，并提供了各种基团完全不对称的三芳基甲烷衍生物，该方法操作简便，反应时间短，催化剂廉价易得，生产成本低，污染少，后处理简单，而且反应具有很好的收率。
