Reactions induced by B-F interaction

Boron is one of the hardest atoms and makes the strongest covalent bond (181 kcal / mol, Table 3.1) with fluorine and so the trivalent organic and inorganic boron compounds strongly interact both with fluoride ion and the organic fluorine in carbon-fluorine bonds. The calculated fluoride affinity proposed by Christe et al. [ 1 ] is also one of the measures for the interaction between fluoride ion and Lewis acids. 

Fluoride-ion-promoted B—C bond activation has been employed for transition-metal-catalyzed C—C bond formation. For example, palladium-catalyzed homo coupling of vinyl bromide (18) is mediated by bis(pinacolato)diboron (19), which is activated by fluoride ion
