Tetraarylmethanes are an important class of molecules that contain four aryl groups bonded to a central carbon atom. The shape/three-dimensionality of these molecules makes them suitable for organic light-emitting diodes (OLEDs), organic solar cells, hydrogen storage, and even drug-delivery. Despite their importance, there are only a few methods available for their preparation. Herein, we report a simple procedure for the preparation of tetraarylmethanes that involves a bismuth-catalyzed Friedel-Crafts cyclization followed by a desulfurization reaction mediated by Raney nickel.

通过Friedel-Crafts环化/脱硫策略合成四芳基甲烷

四芳基甲烷是一类重要的分子,其包含四个与中心碳原子键合的芳基。这些分子的形状/三维尺寸使其适合有机发光二极管(OLED),有机太阳能电池,储氢甚至药物输送。尽管它们很重要,但只有少数几种方法可用于其制备。在此,我们报告了一种制备四芳基甲烷的简单方法,该方法涉及铋催化的Friedel-Crafts环化反应,然后进行阮内镍介导的脱硫反应。
