Synthesis of the Novel Ligand Tris-(3,4-dimethoxylphenyl) phosphine and Its Catalytic Performance in 1-Dodecene Hydroformylation

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.

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 in a two-step procedure from inexpensive 1,2-dimethoxybenezene. Higher catalytic activity was obtained for the homogenous hydroformylation of 1-dodecene at a low P/Rh molar ratio and low temperature when TDMOPP was used as a ligand.Figure optionsDownload as PowerPoint slide
