A geometrical isomer of an acrylonitrile compound represented by the formula (I) or of its salt, or a mixture thereof:
[wherein T is phenyl or pyridyl, which is substituted by R2, Q is phenyl, thienyl, pyridyl or benzyl, which may be substituted by R3, R1 is —C(═O)R4 or —C(═S)R4, R4 is alkyl, alkenyl, alkynyl, alkoxy, alkenyloxy, alkynyloxy, alkylthio, alkenylthio, alkynylthio, cycloalkyl, cycloalkyloxy, cycloalkylthio, —N(R5)R6, phenyl, phenoxy, phenylthio, benzyl, benzyloxy, benzylthio, —J, —O—J or —S—J], wherein the geometrical isomer has a longer retention time when analyzed by reversed phase liquid chromatography in which a packing comprising silica having chemically bonded thereto an alkyl group selected from trimethyl, octyl and octadecyl, is used as the stationary phase, and a polar solvent selected from water, methanol and acetonitrile, is used as the mobile phase, and the geometrical isomer mixture contains such geometrical isomer in a larger proportion.
公式(I)所表示的丙烯腈化合物的几何异构体或其盐或混合物:其中T是苯基或吡啶基,其被R2取代,Q是苯基、噻吩基、吡啶基或苄基,其可以被R3取代,R1是-C(═O)R4或-C(═S)R4,R4是烷基、烯基、炔基、烷氧基、烯氧基、炔氧基、烷硫基、烯硫基、炔硫基、环烷基、环烷氧基、环烷硫基、-N(R5)R6、苯基、苯氧基、苯硫基、苄基、苄氧基、苄硫基、-J、-O-J或-S-J,其中几何异构体在反相液相色谱分析中具有较长的保留时间,该分析中使用具有化学键合到其上的甲基、辛基和十八烷基中选的烷基的硅胶填料作为固定相,使用从水、甲醇和乙腈中选的极性溶剂作为流动相,且几何异构体混合物中包含此类几何异构体的比例较大。
