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.
