The rate-determining step in the ring opening of cyclic acetals by trichloroborane to yield α-chloro-ethers is shown to be consistent with the formation of an oxocarbenium ion. Subsequent reduction provides a general route for the conversion of a diol into a hydroxy-ether. Tribromoborane is a more powerful and dichloroborane a less powerful reagent than trichloroborane.
通过三氯硼烷在环缩醛的开环反应中生成α-氯醚的速率确定步骤表明与氧碳鎓离子的形成是一致的。随后的还原提供了二醇转化为羟基醚的一般途径。与三氯硼烷相比,三溴硼烷是一种更强大的试剂,而二氯硼烷是一种性能较差的试剂。
