Deprotonation of a borohydride: synthesis of a carbene-stabilized boryl anion.

David A Ruiz1, Gaël Ung, Mohand Melaimi, Guy Bertrand.   

Abstract

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-diisopropylphenyl, KHMDS = potassium bis(trimethylsilyl)amide.
