Borontrichloride 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 borontrichloride at room temperature afforded α,α,γ-trichloroalkylnitrile. The Prins-type acylations
