efficient, convenient, and novel one pot approach is described for the synthesis of triarylmethanes by in situ oxidation of benzylalcohols followed by the Friedel–Crafts alkylation of di/trimethoxybenzenes in the presence of BF3·OEt2. The generality of the present method is strengthened by screening a variety of aromatic, aliphatic, and heteroaromatic alcohols with methoxy arenes. Shorter reaction time
描述了一种有效,方便和新颖的一锅法,该方法可通过苄醇的原位氧化,然后在BF 3 ·OEt 2存在下二/三甲氧基苯的Friedel-Crafts烷基化反应来合成三芳基甲烷。通过用甲氧基芳烃筛选各种芳族,脂族和杂芳族醇,可以增强本发明方法的通用性。较短的反应时间,温和的反应条件,良好的收率和广泛的底物范围是该方案的重要特征。
