Abstract

Reaction of 2,5-diethynylpyridine with dimesitylborane, [(Mes)(2)BH](2) (Mes = mesityl = 2,4,6-Me3C6H2), gave the unexpected tris-hydroboration product 1-{(Mes)(2)B)-2-[Z-1-((Mes)(2)B)ethylidene]-5-[E-{(Mes)(2)B)vinyl]-1,2-d ihydropyridine, which has been structurally characterised by single-crystal X-ray diffraction.
