✦ Synopsis

A polymerizable unsymmetric tetradentate Schiff base with one vinyl group 3 was synthesized and copolymerized with styrene in toluene. Mn(III) ion was quantitatively incorporated into the copolymers by the functional moieties. The resulting linear polymer-bound manganese complexes ( 4a and 4b) were used as catalyst under homogeneous condition for selective epoxidation of unfunctionalized olefins (i.e. styrene, amethylstyrene and cyclohexene) at room temperature in the presence of iodosylbenzene (PhIO) as the terminal oxidant. The efficacy of epoxidation using the polymeric catalysts was comparable to that of the monomolecular analog.
