Abstract

Preparation of aryl nitrile through classical Rosenmund-von Braun reaction of aryl bromide resulted in a poor yield (61%) due to a high reaction temperature (165° C) and a lack of efficient procedure for separating from a large quantity of heavy metal waste (Cu salts). To address these issues, a practical synthesis of multifunctional aryl nitriles through cyanation of aryl bromides has been developed with heterogeneous Pd/C used as the catalyst. ...
