  酰基膦配体对铑催化的烯烃氢化硅烷化的影响

  摘要：

  我们合成了一系列的酰基膦，并研究了使用RhCl 3 /酰基膦催化的烯烃的氢化硅烷化。结果表明，RhCl 3 /（二苯基膦基）（苯基）甲酮不仅具有较高的活性，而且具有较高的β-加合物选择性。

  A series of polyethylene glycol‐containing imidazolium‐functionalized phosphine ligands (mPEG‐im‐PPh2) were successfully synthesized and used in the rhodium‐catalyzed hydrosilylation of olefins. The results indicate that the RhCl3/mPEG‐im‐PPh2 catalytic system exhibits both excellent activity and selectivity for the β‐adduct. In addition, the catalytic system may be recycled at least six times.

  A series of carboxyl-functionalized imidazolium salts were synthesized. Hydrosilylation reaction of carboxyl-functionalized imidazolium salts (1b–4b, 1c–3c) exhibited higher levels of styrene conversion and higher levels of β-adduct selectivity. In particular, no ethylbenzene as hydrogenation product could be yielded at all when Rh(PPh3)3Cl/carboxyl-functionalized imidazolium inner salts (1c–3c), respectively

  A series of polyethylene glycol-functionalized imidazolium ionic liquids has been prepared and characterized. These ionic liquids have been successfully applied in the hydrosilylation of alkenes catalyzed by rhodium complexes. The effects of the length of the polyether chain, the amount of ionic liquid, and the reaction temperature on the catalytic performance of hydrosilylation have been investigated. Furthermore, the catalytic system has been tested for the hydrosilylation of different alkenes with triethoxysilane. The new catalytic system exhibits both excellent catalytic activity and selectivity under low-temperature conditions. The catalyst system could be recycled five times with slightly deactivation.
