摘要: 通过色谱跟踪对炔烃的钛氢化反应进行了研究。反应前期可得到高选择性高产率的顺式烯烃,反应后期可得到高选择性高产率的反式烯烃。控制反应时间,用酮类淬息方法分别得到了一系列新的专一立体构型的烯丙醇衍生物。

Abstract: The Titano-hydrogenation of Alkyne hydrocarbons was studied by the method of G.C.track.At the early stage the cis-alkene hydrocarbons were obtained with a higher selectivity and a good yield, but trans-ethenes were obtained with a higher selectivity and a good yield at the later stage of the reaction.Controlling the time of the reaction and quenching with ketones,a series of new stere-ospecific allyl alcohols were obtained.

Key words: Alkyne hydrocarbons, Titano-hydrogenation, Stereo-selectivity, Allyl alcohols
