A convenient and practical method for the synthesis of unsymmetrical triarylmethanes was demonstrated through a one-pot three-component double Friedel–Crafts reaction of various aliphatic, aromatic, or heteroaromatic aldehydes with N,N-dialkylanilines and indoles by using a Brønstedacidicionicliquid as the catalyst. This method was successfully applied under metal- and solvent-free conditions at
通过使用布朗斯台德酸性离子液体,各种脂肪族、芳香族或杂芳香族醛与N , N - 二烷基苯胺和吲哚的一锅三组分双傅克反应,证明了一种方便实用的合成不对称三芳基甲烷的方法作为催化剂。该方法在 80 °C 的无金属和无溶剂条件下成功应用,从广泛的底物中以中等至高产率提供了相应的不对称三芳基甲烷产物。此外,通过定量NMR分析研究了该反应的机理。

A novel synthetic utility of NaICl2 for the preparation of bis(4-dimethaminophenyl)arylmethanes and bis(4-dimethaminophenyl)alkanes is described. In the presence of an aqueous solution of NaICl2, the reaction of arenes with aromatic aldehydes gives corresponding triarylmethane derivatives regioselectively in moderate to good yields. The method is also useful for the preparation of diarylalkane derivatives by using aliphatic aldehydes. Supplemental materials are available for this article.
