Some Reactions of α-Allenic Boronates

Abstract

α-Allenic boronates, readily available in high yield from gem-borazirconcene alkanes, react with iodine to give diiodo adducts that when treated with sodium acetate provide 2-iodo-1,3-butadienes. Alternatively, hydrozirconation of the α-allenic boronates followed by treatment with D₂O occurs regioselectively to place deuterium in the allylic position.
