| Abstract: | The new economic and effective method for the synthesis of aromatic nitriles is found via the realization of a new reaction between benzyl alcohols with K4Fe(CN)6] using Cu2O as the catalyst.The reaction conditions such as solvent,catalyst,temperature and oxygen pressure are optimized,and sixteen aromatic nitriles are synthesized under the optimum reaction conditions,in which the isolated yields are 62%—87%.The reaction mechanism is proposed that Benzyl alcohols undergo the aerobic oxidative dehydrogenation,followed by the conversion of aryl formaldehyde into aryl nitriles.Compared with the related methods,the substrates are replaced by cheaper benzyl alcohols.Moreover,the used catalyst Cu2O is a heterogeneous catalyst that can be recycled,which obviously decreases the reaction cost. |
