摘要:钛配合物还原剂双组分催化剂对不饱和烃类的加氢反应引起了人们的广泛关注.我们曾报道过以纳米氢化钠(NaH)为助剂(还原剂)与茂钛配合物组成的双组分催化剂对不饱和烃类的加氢反应[1,2],这类催化剂在温和条件下显示出很高的活性,但稳定性稍差.最近我们...
The hydrogenation of terminal olefins was catalyzed by titanocenes with various substituted groups in combination with nanometric sodium hydride. When the steric hindrance of the substituted group on the cyclopentadienyl ring was large (for instance, six membered ring or seven membered ring), the titanium complex gave extremely high catalytic activity with fairly good stability. At normal temperature and pressure, a maximum turnover frequency (TOF initial ) of 298 mol/(mol·s) in the hydrogenation of 1 hexene and a turnover (TO) of 118000 mol/mol in the hydrogenation of styrene were obtained. These catalysts exhibited very special selectivity to the olefin substrate. Only the terminal olefins could be hydrogenated by using this kind of catalytic system.
