2, 3-Bis (bromomethyl)-l, 3-butadiene (1) was prepared by zinc-induced debromination of 1, 4-dibromo-2, 3-bis (bromomethyl)-2-butene (2). The versatility of 1 as a synthetic intermediate was demonstrated through consecutive use of its allylic bromides and conjugated diene functions, with eventual further modification of the primary reaction products. Coupling of 1 with vinylmagnesium chloride or ethynylmagnesium bromide gave ...
