Design and Construction of Novel Frustrated Lewis Pairs Based on Modified Lewis Acid B(C6F5)3
CrystalsThis study aims to systematically investigate the influence of substituent effects on the strength of Lewis acid–base interactions in frustrated Lewis pairs (FLPs). Specifically, -C6F5 groups of the classical Lewis acid B(C6F5)3 are sequentially replaced
