Phosphorylated Imidazole-Functionalized Chloromethylated Polystyrene-Supported Rhodium Catalyst for Hydroformylation of Dihydrofurans
A phosphorylated imidazole-functionalized chloromethylated polystyrene carrier was synthesized by grafting phosphine–nitrogen ligands onto chloromethylated polystyrene resin, followed by coordination with rhodium metal. This approach provides a foundation for the design diversity of supported ligands. The catalytic activity of the prepared supported catalyst was evaluated in the hydroformylation reaction of 2,5-dihydrofuran (2,5-DHF). In this study, a series of phosphorylated imidazole-functionalized rhodium catalysts were successfully prepared and characterized using FT-IR Spectroscopy, TG, SEM, and XPS. The coordination relationships between the rhodium and the phosphorus and nitrogen species within the catalyst were confirmed. The conversion of 2,5-DHF reached 58.4%, with a selectivity of 97.1% for 3-formyltetrahydrofuran using Rh (CO)2(acac)@PS-IM-PPh2. Notably, product selectivity remained high after five cycles of catalyst use. The catalyst system was easily recoverable, and good selectivity was maintained across a range of substrates. The introduction of phosphine into the imidazole group of the organic polymer support creates a nitrogen-phosphine synergistic ligand. Furthermore, by linking a diverse array of substituents, various imidazole-based ionic phosphine ligands can be derived, providing a basis for the design diversity of supported ligands.
期刊介绍:
Catalysis Letters aim is the rapid publication of outstanding and high-impact original research articles in catalysis. The scope of the journal covers a broad range of topics in all fields of both applied and theoretical catalysis, including heterogeneous, homogeneous and biocatalysis.
The high-quality original research articles published in Catalysis Letters are subject to rigorous peer review. Accepted papers are published online first and subsequently in print issues. All contributions must include a graphical abstract. Manuscripts should be written in English and the responsibility lies with the authors to ensure that they are grammatically and linguistically correct. Authors for whom English is not the working language are encouraged to consider using a professional language-editing service before submitting their manuscripts.
