Deprotonation of a Borohydride: Synthesis of a Carbene-Stabilized Boryl Anion

An acidic hydride! Thanks to the presence of a π‐acceptor cyclic alkyl amino carbene and of two electron‐withdrawing nitrile groups, a borohydride reacts with a base to give a carbene‐stabilized boryl anion, which reacts with carbon and metal electrophiles at the boron center. Dipp=2,6‐diisopropylph...
