By grafting nitrogen-containing complexes onto ZSM-5 mesoporous material and then supporting a cobalt catalyst in situ, the methoxycarbonylation of diisobutylene (DIB) was achieved. Moreover, a series of functionalized ZSM-5 mesoporous materials containing different nitrogen complexes were synthesized and characterized by FT-IR, N₂ adsorption–desorption isotherms, XRD, SEM, and X-ray photoelectron spectroscopy (XPS). Subsequently, the catalytic activity of functionalized ZSM-5 mesoporous materials and the reaction parameters in the methoxycarbonylation of DIB were investigated. The results revealed that the conversion of DIB was 88.3% and the selectivity for methyl isononanoate was 93.4% under solvent-free conditions at 6.0 MPa and 140 °C for 10 h by using the catalyst ZSM-5iCPdPy@Co₂(CO)₈. The potential mechanism for this catalytic reaction was also put forth. Admittedly, these inexpensive and easy-to-recover heterogeneous catalysts can replace the noble metal palladium complexes on a laboratory scale to achieve partial olefin carbonylation reactions.

通过将含氮配合物接枝到 ZSM-5 介孔材料上，然后原位负载钴催化剂，实现了二异丁烯 (DIB) 的甲氧基羰基化反应。此外，还合成了一系列含有不同氮络合物的功能化ZSM-5介孔材料，并通过FT-IR、N ₂吸附-脱附等温线、XRD、SEM和X射线光电子能谱(XPS)对其进行了表征。随后，研究了功能化 ZSM-5 介孔材料的催化活性和 DIB 甲氧基羰基化反应的反应参数。结果表明，使用ZSM-5iCPdPy@Co 2 催化剂在无溶剂、6.0 MPa、140 ℃、10 h条件下，DIB的转化率为88.3%，异壬酸甲酯的选择性为93.4% _。(CO) ₈。还提出了该催化反应的潜在机理。不可否认，这些廉价且易于回收的多相催化剂可以在实验室规模上替代贵金属钯配合物，实现部分烯烃羰基化反应。
