摘要： 合成了以联苯为骨架, 以吲哚为取代基的双膦配体, 并研究了该配体与 Rh(acac)(CO)2 原位生成的催化剂在 2-丁烯氢甲酰化反应中的催化性能. 考察了膦/铑比、反应温度、反应压力以及 2-丁烯与 Rh(acac)(CO)2 摩尔比等因素对反应活性及区域选择性的影响. 结果表明, 在 60 °C 反应时, 醛的正异比高达 28.5; 当压力为 2.0 MPa 时, 反应 TOF 值可达 660 h?1.

Abstract: A new biphosphorus ligand has been developed and applied in the rhodium-catalyzed regioselective hydroformylation of 2-butene. The effects of ligand/Rh ratio, reaction temperature, reaction pressure, and substrate/catalyst molar ratio were investigated. High activity and regioselectivity were achieved. The n-aldehyde/iso-aldehyde ratio of about 28.5 was obtained at 60 °C, and the TOF increased to 660 h-1 at the pressure of 2.0 MPa.
