Boron trichloride was found to be a useful Lewis acid for the Prins-type reaction of alkenes with electron-deficient nitriles. In its presence, monosubstituted alkenes react with trichloroacetonitrile, giving dichloroazirine derivatives in high yields. Further exposure of the azirine derivative to boron trichloride at room temperature afforded α,α,γ-trichloroalkylnitrile. The Prins-type acylations
三氯化硼被发现是一种有用的路易斯酸,可用于烯烃与缺电子腈的 Prins 型反应。在它的存在下,单取代烯烃与三氯乙腈反应,以高产率得到二氯氮丙啶衍生物。在室温下将氮丙啶衍生物进一步暴露于三氯化硼,得到 α,α,γ-三氯烷基腈。还描述了 1,1-二取代烯烃与三氯乙腈的 Prins 型酰化反应。
