Intramolecular hydroboration is demonstrated starting from homoallylic amine boranes upon activation by iodine. The process involves a B-iodoborane complex as the intermediate and may occur via internal displacement of iodide by the alkene to generate a cationic borane-alkene pi-complex on the way to hydroboration products. The reaction can be carried out using a catalytic amount of iodine.
分子内硼氢化反应是从碘活化的高烯丙基胺硼烷开始进行演示的。该过程涉及一种硼碘硼烷络合物作为中间体，并且可能通过烯烃对碘化物的分子内取代，在生成硼氢化产物的过程中产生阳离子硼烷 - 烯烃π络合物。该反应可以使用催化量的碘来进行。
