I (H2L; R = polymer-bonded benzyl) was prepared by the reaction of I (R = H) with chloromethylated polystyrene in DMF containing anhydrous K2CO3. CoL was prepared by the reaction of I (R = polymer-bonded benzyl) with Co(OAc)2 in DMF. In the catalytic oxidation of hydroquinone to quinone, the conversion rates of hydroquinone to quinone in the presence of CoL (R = Me) for 2 and 4 h were 82 and 100%, resp., whereas in the presence of CoL (R = polymer-bonded benzyl) the conversion rates were 53 and 75%, resp. CoL (R = Me) was difficult to reuse as a catalyst, whereas the catalytic activity of II (R = polymer-bonded benzyl) was unchanged even after 3 used.
