Halogenated triarylboranes (BAr3) have been known for decades, however it has only been since the surge of interest in main group catalysis that their application as strong Lewis acid catalysts has been recognised. This review aims to look past the popular tris(pentafluorophenyl)borane [B(C6F5)3] to the other halogenated triarylboranes, to give a greater breadth of understanding as to how tuning the Lewis acidity of BAr3 by modifications of the aryl rings can lead to improved reactivity. In this review, a discussion on Lewis acidity determination of boranes is given, the synthesis of these boranes is discussed, and examples of how they are being used for catalysis and frustrated Lewis pair (FLP) chemistry are explained.

卤代三芳基硼烷：合成，性质及在催化中的应用。

卤代三芳基硼烷（BAr3）已有数十年的历史，但是自从对主基团催化的兴趣激增以来，人们才认识到它们作为强路易斯酸催化剂的应用。这篇综述的目的是将流行的三（五氟苯基）硼烷[B（C6F5）3]移到其他卤代三芳基硼烷上，以更广泛地了解如何通过修饰芳基环来调节BAr3的路易斯酸度，从而导致改善反应性。在这篇综述中，讨论了硼烷的路易斯酸度测定，讨论了这些硼烷的合成，并举例说明了它们如何用于催化和沮丧的路易斯对（FLP）化学。
