Lithium, sodium, and potassium enolates reacted with bisaminoboron halides to give bisaminoboron enolates 1a−5c. Specifically, the potassium enolate of tert-butyl methyl ketone reacted with bis(diisopropylamino)boron chloride in THF at room temperature within 1 h to give the bis(diisopropylamino)boron enolate of tert-butyl methyl ketone (3b) in 61−84% isolated yields. Under similar conditions, the
