The invention relates to a process for preparing 1-octene by reacting 1,3-butadiene with a telogen of the formula H—X—Y—H, where X is O, N, S or P and Y is C, N or Si and X and Y bear, depending on their valence, further substituents, in the presence of a telomerization catalyst to form a telomer of the formula H

本发明涉及一种制备1-辛烯的方法,包括在催化剂的存在下,通过将1,3-丁二烯与公式H-X-Y-H的缩合剂反应来形成缩合物,其中X为O、N、S或P,Y为C、N或Si,且X和Y根据它们的价,具有进一步的取代基。然后,部分加氢缩合物以形成公式H3C-CH2-CH2-CH2-CH2-CH═CH-CH2-X-Y-H的1-取代2-辛烯,最后解离1-取代2-辛烯以得到1-辛烯。
