Reaction of 2-benzothiazolylmagnesium bromide with (diethylamino)dichloroborane took place with trisheteroarylation instead of diheteroarylation at the boron atom, and tris(2-benzothiazolyl)borane was isolated as its diethylamine adduct. The mol. structure of the title adduct was confirmed by x-ray crystallog. anal.
