摘要
Continuous‐flow syntheses using immobilized catalysts can offer efficient chemical processes with easy separation and purification. In particular, porous polymers have gained significant interests for their applications to catalytic systems in the field of organic chemistry. The porous polymers are recognized for their large surface area, high chemical stability, facile modulation of surface chemistry, and cost‐effectiveness. It is crucial to immobilize transition‐metal catalysts due to their difficult separation and high toxicity. Supported phosphine ligands represent a noteworthy system for the effective immobilization of metal catalysts and modulation of catalytic properties. Researchers have been actively pursuing strategies involving phosphine‐metal complexes supported on porous polymers, aiming for high activities, durabilities, selectivities, and applicability to continuous‐flow systems. This review provides a concise overview of phosphine‐metal complexes supported on porous polymers for continuous‐flow catalytic reactions. Polymer catalysts are categorized based on pore sizes, including micro‐, meso‐, and macroporous polymers. The characteristics of these porous polymers are explored concerning their efficiency in immobilized catalysis and continuous‐flow systems.
