Procedure

cis,trans-Muconic acid (38.3 g, 269.7 mmol) is dissolved in THF (400 mL) at room temperature and a crystal of iodine (247 mg, 0.972 mmol) is added. The reaction mixture is allowed to stir at room temperature for 24 hours. The precipitate is obtained by filtration, washed with ice-cold tetrahydrofuran (2×) and dried under reduced pressure to yield 33.2 g (a 86 percent yield) of trans,trans-muconic acid. The reaction sequence is shown in FIG. 3.
