Procedure

Cis,trans-muconic acid (19 g, 133.8 mmol) is dissolved in THF (250 mL) at room temperature and a crystal of iodine (160 mg, 0.63 mmol, 0.5 mole percent) is added. The reaction is performed in the presence of ambient light in the laboratory. The reaction mixture is allowed to stir at room temperature for 5 hours and the precipitant is filtered, washed with acetonitrile and dried under reduced pressure to yield 16 g of trans, trans-muconic acid, an 84 percent yield.
