一种新型亚磷酰胺配体的合成及其在费托烯烃氢甲酰反应中的应用

novel phosphinamide ligand (L) was synthesized and structurally characterized, and subsequently employed in the construction of a homogeneous Rh-based catalytic system for the hydroformylation of Fischer-Tropsch olefins. By systematically optimizing reaction parameters such as ligand-to-rhodium molar ratio, reaction temperature, and syngas pressure, the optimal conditions (P/Rh = 20, 60 C, 2.0 MPa) were determined. Under these conditions, the catalyst system exhibited excellent conversion rates and aldehyde selectivity across a range of substrates including FT-C6, FT-C7, FT-C8, and dicyclopentadiene, demonstrating good substrate compatibility. The study confirms that ligand L effectively promotes the formation of catalytically active Rh species, offering valuable insights for the development of efficient homogeneous hydroformylation systems and the design of phosphine ligands.
