    • Provided is a simple and industrially advantageous method for producing 2,7-octadien-1-ol, in which an expensive palladium catalyst is recovered in high efficiency and the reaction rate per atom of palladium is enhanced. Specifically, provided is a method for producing 2,7-octadien-1-ol by subjecting butadiene and water to a telomerization in the presence of a palladium catalyst containing a water-soluble triarylphosphine having two or more sulfonate groups in the molecule and a palladium compound, a tertiary amine, and carbon dioxide, including a step of mixing the telomerization solution obtained by the telomerization with an organic solvent having a dielectric constant at 25° C. of 2 to 18, followed by carrying out phase separation in the presence of carbon dioxide, thereby obtaining 2,7-octadien-1-ol from an organic phase while recovering an aqueous phase including the palladium catalyst. By this production method, the selectivity for 2,7-octadien-1-ol is enhanced.
    • 提供了一种简单且工业上有利的生产2,7-辛二烯-1-醇的方法,其中以高效率回收昂贵的钯催化剂,并且每个钯原子的反应速率增强。 具体地说,提供了在含有分子中具有2个以上磺酸酯基的水溶性三芳基膦的钯催化剂的存在下,使丁二烯和水进行调聚,得到2,7-辛二烯-1-醇的方法, 化合物,叔胺和二氧化碳,包括将通过调聚获得的调聚溶液与介电常数在25℃下的有机溶剂混合2至18的步骤,然后在存在下进行相分离 从而从有机相中获得2,7-辛二烯-1-醇,同时回收包括钯催化剂的水相。 通过该制备方法,增强了对2,7-辛二烯-1-醇的选择性。
