Various arylbis(trifluoromethylsulfonyl)methanes (1) have been synthesized by reacting the corresponding benzylic halides with sodium trifluoromethanesulfinate and then with triflic anhydride. In addition, when the aryl group of 1 is a pentafluorophenyl group, the nucleophilic para-substitution of the aryl group with alkyllithiums and sodium alkoxides occurs. This reaction is useful for the design of new Brønsted acids.
通过将相应的苄基卤化物与三氟甲烷亚硫酸钠反应,然后再与三氟甲磺酸酐反应,合成了多种芳香基双(三氟甲磺酰)甲烷 (1)。此外,当1中的芳基是五氟苯基时,芳基的亲核性对位取代反应可以通过烷基锂和烷氧化钠实现。这一反应对于设计新型布朗斯特酸具有实用价值。
