Procedure

cis,trans-muconic acid (103 mg, 0.767 mmol) is dissolved in ethyl acetate (10 mL) at room temperature and a crystal of iodine (27 mg, 0.106 mmol) is added. The reaction mixture is allowed to stir at room temperature for 24 hours. The precipitate is filtered, washed with ice-cold acetonitrile and dried under reduced pressure to yield 60 mg of trans,trans-muconic acid, a 58 percent yield.
