在近似工业反应条件下(H2/CO=1:1, 1.0MPa, 70℃), 应用加温加压原位核磁共振技术, 考察了铑膦配合物催化剂HRh(CO)(PPh3)3-PPh3体系的烯烃醛化反应。结果表明,在烯烃醛化反应条件下, 反应液中存在羰基氢化铑中间配合物, 并在^1H NMR获得了该配合物中Rh-H键的质子讯号。

Under the industrial reaction conditions (H2/CO = 1:1, 1.0 MPa, 70?, the hydroformylation of olefins with rhodium-phosphine complex catalyst HRh(CO)(PPh3)3 is studied by using in situ NMR techniques. The results show that the intermediate is a hydride-rhodium carbonyl complex and the proton signal with a Rh-H bond in the 1H NMR has been observed
