반응 단계
500 ml of glacial acetic acid, 50.8 g of 4-acetoxy-4'-acetylbiphenyl, 0.8 g of cobalt(II) acetate and 12.0 g of manganese(II) acetate were refluxed in a 1 l double-walled flanged reactor equipped with an intensive stirrer and baffles, and the mixture was gassed with air via a valve in the base. After 4 hours, the mixture was cooled and the product was filtered off under suction, washed with water and dried. 26.1 g (51% yield) of 4-acetoxybiphenyl-4'-carboxylic acid having a purity of >98% (HPLC) were obtained.
