Protocols for the synthesis of the bulky polyfluorinated triarylboranes 2,6-(C F ) C F B(C F ) (1), 2,6-(C F ) C F B[3,5-(CF ) C H ] (2), 2,4,6-(C F ) C H B(C F ) (3), 2,4,6-(C F ) C H B[3,5-(CF ) C H ] (4) were developed. All boranes are water tolerant and according to the Gutmann-Beckett method, 1-3 display Lewis acidities larger than that of the prominent B(C F ) .
合成大体积多氟三芳基硼烷 2,6-(C F ) C F B(C F ) (1)、2,6-(C F ) C F B[3,5-(CF ) C H ] (2)、2,4,6-(C F ) C H B(C F ) (3)、2,4,6-(C F ) C H B[3,5-(CF ) C H ] (4)的方法已经开发出来。所有硼烷都耐水，根据 Gutmann-Beckett 方法，1-3 的路易斯酸度大于著名的 B(C F ) 。
