Lewis Acidic Boranes in Frustrated
Lewis Pair Chemistry
Theodore A. Gazis, Darren Willcox, and Rebecca L. Melen
Abstract From their inception, boron-based frustrated Lewis pairs have garnered
significant scientific attention thanks to the multitude of potential applications they
can be employed in. The ever-expanding library of halogenated triarylboranes has
enabled this interest to flourish. In this chapter, we explore the significant breakthroughs that have been achieved in the use of triarylboranes in frustrated Lewis pair
chemistry including borane synthesis, water tolerance and chirality.
