The reaction of arylboronic acids with bismuth(III) nitrate pentahydrate resulted in a series of nitroarenes when the reaction was carried out under microwave (120 ℃) for 1 min in 1,2-dichloroethane. Compared with traditional heating condition, the method of microwave condition for the preparation of nitroarenes was simple, efficient, time-saving, and of less by-products. In addition, possible free radical mechanism was proposed.
