A process for selectively hydroformylating a diolefin, which comprises reacting a (1-arylethenyl)-vinylbenzene with carbon monoxide and hydrogen under the conditions of 40 to 200°C in reaction temperature and 5 kg/cm2 or above in reaction pressure in the presence of a transition metal carbonylation catalyst to thereby selectively hydroformylating only the vinyl group and produce α-((1-arylethenyllphenyl)-propionaldehyde. The starting material to be hydroformylated may be a mixture of the vinylbenzene with a 1,1-di(substituted aryl)ethylene not substituted by a vinyl group.
一种选择性地使二烯烃加氢甲酰化的工艺,包括在过渡金属羰基化催化剂存在下,在反应温度为 40 至 200°C 和反应压力为 5 kg/cm2 或以上的条件下,使(1-芳基乙烯基)-乙烯基苯与一氧化碳和氢反应,从而只选择性地使乙烯基加氢甲酰化,生成 α-((1-芳基乙烯基苯基)-丙醛。要进行氢甲酰化的起始原料可以是乙烯基苯与未被乙烯基取代的 1,1-二(取代芳基)乙烯的混合物。
