Iodine → Muconic Acid

関与物質

反応手順

A mixture containing cis,trans muconic acid (1.00 g), a catalytic amount of iodine (53 mg, 3.0 mole percent), and acetonitrile (35 ml) is heated to reflux for 11 hours. The reaction is performed in the presence of ambient light in the laboratory. After cooling to room temperature, the precipitated solid is filtered off and washed with acetonitrile. After drying under high vacuum, 0.80 g (80 percent yield) of pure trans,trans muconic acid are present as a tan-colored powder. The material obtained by this procedure from cis,trans muconic acid is identical to the material obtained from cis,cis muconic acid by the previous procedure.
