Abstract We developed a triphasic (solid–organic–aqueous) continuous‐flow reaction system for the chemoselective oxidation of primary and secondary alcohols, using 2,2,6,6‐tetramethylpiperidine‐1‐oxyl (TEMPO) immobilized on polyethylene‐ g ‐polyacrylic acid graft polymer ( g ‐TEMPO). g ‐TEMPO exhibited higher contact efficiency than TEMPO supported on silica or cross‐linked polystyrene under immiscible‐flow conditions, and maintained excellent conversion for at least 9 days with no loss of catalytic activity.
