    • A process for producing alkenyl-substituted aromatic hydrocarbons which comprises alkenylating an alkyl-substituted aromatic hydrocarbon having a hydrogen atom at the alpha -position of the side chain with a conjugated diene, wherein use is made of a catalyst obtained by the action of an alkali metal compound and either an alkali metal or an alkali metal hybride on a metal oxide selected between alumina and hydrotalcite by heating in a specific temperature range; and another process for producing an alkenyl-substituted aromatic hydrocarbon, characterized by conducting the reaction in the presence of an alkylaminopyridine represented by formula (1) (wherein R1 represents hydrogen or C1-6 alkyl and R2 represents C1-6 alkyl) using a catalyst comprising sodium metal, potassium metal, or an alloy thereof, a catalyst having any of these supported on a support of an inorganic compound, or a catalyst obtained by the action of an alkali metal compound and either an alkali metal or an alkali metal hybride on a metal oxide selected among alumina, alkaline earth oxides, hydrotalcite, silica-alumina, and zeolite by heating in a temperature range of 70 to 700 DEG C.
    • 一种制备烯基取代的芳族烃的方法,其包括在共轭二烯的侧链的α-位上使具有氢原子的烷基取代的芳族烃链烯基化,其中使用由碱的作用获得的催化剂 金属化合物和通过在特定温度范围内加热而选择在氧化铝和水滑石之间的金属氧化物上的碱金属或碱金属混合物; 和另一种制备烯基取代的芳族烃的方法,其特征在于使用催化剂在式(1)表示的烷基氨基吡啶存在下进行反应(其中R 1表示氢或C 1-6烷基,R 2表示C 1-6烷基) 包括金属钠,金属钾或其合金,其中任一种负载在无机化合物的载体上的催化剂,或通过碱金属化合物和碱金属或碱金属混合物的作用获得的催化剂 选自氧化铝,碱土金属氧化物,水滑石,二氧化硅 - 氧化铝和沸石的金属氧化物,在70〜700℃的温度范围内加热。
