AI Technical Summary
Existing phosphoramide ligands suffer from poor structural stability, sensitivity to light or water, complex synthesis processes, or low yields, which limit their widespread application in hydroformylation reactions.
By introducing phosphoramidine ligands with specific nitrogen-containing heterocyclic structures, a two-step synthetic route is adopted. The resulting ligands form catalysts with transition metals for olefin hydroformylation reactions, thereby improving catalytic activity and stability.
The efficient preparation of phosphoramide ligands was achieved, and the resulting catalyst exhibits high activity, selectivity, and stability in the hydroformylation of olefins, making it suitable for high-carbon olefin reactions and avoiding deactivation problems during high-temperature separation.
