A highly efficient arylation of para-quinone methides (p-QMs) with N,N-dimethylaniline under solvent free condition has been developed, which proceeded via a para-toluenesulfonic acid (TsOH)-promoted 1,6-conjugated addition pathway. This methodology provided a green and sustainable methodology to construct various novel unsymmetrical triarylmethanes (TAMs) with the advantages of good functional group tolerance, scalability, and regioselectivity.

对醌甲基化物的无溶剂 1,6-共轭芳基化：一种更环保的不对称三芳基甲烷方法

已开发出在无溶剂条件下对-醌甲基化物 ( p- QMs) 与N,N-二甲基苯胺的高效芳基化反应，该反应通过对-甲苯磺酸 (TsOH) 促进的 1,6-共轭加成途径进行。该方法为构建各种新型不对称三芳基甲烷（TAM）提供了一种绿色和可持续的方法，具有良好的官能团耐受性、可扩展性和区域选择性等优点。
