A protocol for the regioselective cleavage of unsymmetrical alkyl ethers to generate alkyl alcohol and alkyl bromide products is described. A mixture of trihaloboranes triggers this conversion and exhibits improved reactivity profiles (regioselectivity and yield) compared with BBr3 alone. Additionally, this procedure allows the efficient synthesis of (B–Cl) dialkyl boronate esters. There are limited
描述了用于不对称烷基醚的区域选择性裂解以产生烷基醇和烷基溴化物产物的方案。与单独的BBr 3相比,三卤呋喃酮的混合物触发了这种转化并显示出改善的反应性分布(区域选择性和产率)。此外,该程序可以有效合成(B–Cl)硼酸二烷基酯。产生无环二烷氧基硼酰氯的方法是有限的,这些中间体在主族化学中构成重要的合成子。
