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。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。Dimethylacetylene (tolane) suffered hydrogenation in the presence of (RCp)_2TiCl_2. 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.
