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

Aminoboroxines have been prepared from the reaction of chlorobis(dialkylamino)boranes with mercuric oxide. Chlorobis(di-i-propylamino)borane failed to react and the isolation of bis(n-butoxyphenylboryl)oxide from the reaction of n-butoxychlorophenylborane and mercuric oxide was not successful.

The reactivity of ClB(NEt2)2 and ClB(NiPr2)2 towards organomagnesium or organolithium derivatives was studied. ClB(NiPr2)2 proved to be an excellent reagent for the preparation of pure boronic derivatives RB(NiPr2)2 which can be used for an efficient synthesis of oxazaborolidines, including Corey's CBS catalyst.
