    • 12 Cobalt(III) acetate was prepared by ozonation of cobalt(II) according to: Lande, S. S.; Falk, C. D.; Kochi, J. K. J. Inorg. Nucl Chem. 1971, 33, 4101-4109. General oxidation procedure: 0.30 g (2.5 mmol) of poly(4-methyl-styrene) and 0.85 g (20 mmol) of lithium chloride were dissolved in a mixture of 15 mL of glacial acetic acid and 15 mL of benzene under nitrogen. The temperature was raised to 50 °C, and 1.18 g (5.0 mmol) of cobalt(III) acetate was added to form a dark green solution. After 2 h, the reaction mixture was cooled and filtered and the benzene component removed on a rotary evaporator. The remaining solution of oxidized polymer and cobalt salts was precipitated into 200 mL of 4:1 methanol/water. The white precipitate was collected by filtration, washed, and dried under vacuum at 60 °C overnight to yield typically around 90% of polymeric product.

    • A 0.20 g sample of 20% poly(4-methylstyrene-co-4-(chloromethyl)styrene) and 0.30 g sodium hydrogen carbonate were stirred in 18 mL of dimethyl sulfoxide for 6 h at 155 °C. The product was filtered, washed with dimethyl sulfoxide and hot water, and dried at 60 °C under vacuum overnight.
