A new solid acid Nafion-H, a perfluorinated sulfonic acid resin, catalyzed microwave-assisted synthesis of triarylmethanes is described. Various benzaldehydes react readily with arenes to provide the corresponding triarylmethanes in good to excellent yields. The reactions were carried out under solvent free conditions under microwave irradiation in a pressure vessel. The solvent free microwave irradiation
描述了一种新的固体酸 Nafion-H,一种全氟磺酸树脂,催化微波辅助合成三芳基甲烷。各种苯甲醛很容易与芳烃反应,以良好到极好的收率提供相应的三芳基甲烷。反应在无溶剂条件下在微波辐射下在压力容器中进行。与在压力管中进行的传统加热方法相比,无溶剂微波辐射方法似乎是一种环境友好的合成方案,可在明显更短的反应时间内提供产品。
