Protocols for the synthesis of the bulky polyfluorinated triarylboranes 2,6‐(C 6 F 5 ) 2 C 6 F 3 B(C 6 F 5 ) 2 ( 1 ), 2,6‐(C 6 F 5 ) 2 C 6 F 3 B[3,5‐(CF 3 ) 2 C 6 H 3 ] ( 2 ), 2,4,6‐(C 6 F 5 ) 3 C 6 H 2 B(C 6 F 5 ) 2 ( 3 ), 2,4,6‐(C 6 F 5 ) 3 C 6 H 2 B[3,5‐(CF 3 ) 2 C 6 H 3 ] ( 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 6 F 5 ) 3 .
