An intramolecular 1,2-boryl-anion migration from boron to carbon has been achieved by selective activation of the π system in [(vinyl)B<sub>2</sub> Pin<sub>2</sub> )]<sup>-</sup> using "soft" BR<sub>3</sub> electrophiles (BR<sub>3</sub> =BPh<sub>3</sub> or 9-aryl-BBN). The soft character is key to ensure 1,2-migration proceeds instead of oxygen coordination/B-O activation. The BR<sub>3</sub> -induced 1,2-boryl-anion migration represents a triple borylation of a vinyl Grignard reagent using only ...[more]
