摘　　要：将合成的三(3,4-二甲氧基苯基)膦(TDMOPP)用作Rh催化剂配体,并用于1-十二烯氢甲酰化反应,考察了膦/铑比和反应温度对Rh-TDMOPP催化剂活性和选择性的影响.结果表明,在膦/铑比与反应温度较低时,Rh-TDMOPP活性是Rh-三苯基膦催化剂的3倍.Tris-（3,4-dimethoxylphenyl）phosphine（TDMOPP） was synthesized and used as a ligand for the homogenous hydroformylation of 1-dodecene.The effects of the P/Rh molar ratio and reaction temperature on the activity and regioselectivity were investigated.The results showed that the activity of TDMOPP was about two times higher than that of the traditional triphenylphosphine at a low P/Rh and temperature.
