Our interest in C–F bond activation prompted an investigation of the reactions of PhC(O)CF3 with a superbasic proazaphosphatrane (Verkade's base) and a corresponding FLP.

The understanding of the mechanism by which frustrated Lewis pairs activate small molecules has been evolving with the discovery that both heterolytic and homolytic bond activation is possible. Herein we characterized a novel Lewis acidic aminoborane containing a phenothiazyl substituent and demonstrate its potential to catalytically promote the dehydrocoupling of tin hydrides. The reactivity observed implies this species promotes homolytic bond activation, however computational analysis suggests a heterolytic mechanism for this reaction. This result represents the first frustrated Lewis pair system to blur the lines between heterolytic and homolytic reactivity.

In the past years, the chemistry of Frustrated Lewis pairs enabled a plethora of transformations that would otherwise only be possible using transition metal catalysts. Of particular interest are the C-H bond activation and borylation reactions, which is the subject of this review. The FLP borylation chemistry is compared with the early borylation methodologies using strongly electrophilic borenium ions. We present the mechanism of the C-H borylation using inter- and intramolecular Lewis pairs, along with some applications of these transformations.
