摘要: 最近我们发现了在催化量(RCp)2TjCl2-PriMgBr存在和常温常压下二苯乙炔的加氢反应[1]。该反应以H2为还原剂,经顺、反式二苯乙烯可定量地得到二苯乙烷。它比以格氏试剂为还原剂的钛氢化反应更具优越性[2-4]

Abstract: Dimethylacetylene (tolane) suffered hydrogenation in the presence of (RCp)2TiCl2. The influences of the catalyst structure on the selectivity of the reaction have been studied.Results indieated that cis-olefins as well as trans-olefins could be obtained by varying R in the catalyst and under suitable reaction conditions.

Key words: dimethylacetylene, hydrogenation, selectivity, catalyst, titan-hydrogen complex
