摘　　要：研究了在阳离子表面活性剂存在下水/有机两相中水溶性铑配合物RhCl(CO)(TPPTS)2(TPPTS:P(m-C6H4SO3Na)3)催化双环戊二烯氢甲酰化反应,考察了反应温度、催化剂浓度、不同水溶性膦配体TPPTS和TPPDS(C6H5P(m-C6H4SO3Na)2),以及表面活性剂结构对催化反应的影响.结果表明,配体TPPTS比TPPDS表现出更好的助催化效果;阳离子表面活性剂C16H33N(CH3)2CnH2n+1Br(n=1,8,12,16)的加入可大大加速反应,但加速作用随着其中CnH2n+1Br(n=1,8,12,16)链长的增加而减弱;在阳离子表面活性剂(0.05～5.00mmol/L)存在下,双环戊二烯的转化率随表面活性剂浓度的增加先增加后降低.含催化剂的水相循环使用4次后,催化活性和区域选择性没有明显下降.Dicyclopentadiene （DCPD） hydroformylation catalyzed by the water soluble rhodium complex RhCl（CO）（TPPTS）2 （TPPTS：P（m-C6H4SO3Na）3） was studied in an aqueous/organic two phase system containing a cationic surfactant.The effects of various reaction parameters such as reaction temperature,catalyst concentration,water soluble phosphine TPPTS or TPPDS （C6H5P（m-C6H4SO3Na）2）,and surfactant structure were examined.The catalytic activity was better with the ligand TPPTS than with TPPDS.The reaction was accelerated by the addition of the cationic surfactant C16H33N（CH3）2CnH2n＋1Br （n=1,8,12,16） but the accelerating effect was attenuated with an increase of the n value.In the presence of the surfactant,the DCPD conversion increased initially and then decreased as the rhodium concentration increased in the range of 0.05-5.00 mmol/L.The catalyst containing aqueous phase was reused four times without significant decrease in activity and regioselectivity.
