<p>PURPOSE:To obtain the title compound by allowing an oxirane with a specific compound in the presence of silicon tetrafluoride to effect position-specific reaction of the oxirane. CONSTITUTION:In the presence of silicon tetrafluoride, an oxirane of formula I (R<1>, R<2>, R<3>, R<4> may be identical or different, H, alkyl, aryl, nitrile, alkoxyalkyl or R<1> and R<2> or R<1> and R<3> may incorporate to form a ring) is allowed to react with a nitrile of formula II (R<5> is alkyl, aryl), preferably at a weight ratio of 1 of the compound of formula I to 200-300 of the compound of formula II, at 0-90 deg.C, preferably 0-20 deg.C, to give the compound of formula III. The compound of formula II is acetonitrile, propionitrile, benzonitrile or tolynitrile.</p> |
