Herein we report a novel magnetically recoverable lanthanum hydroxide nanoparticles for oxidative synthesis of nitriles directly from corresponding alcohols with ammonia as nitrogen source. The procedure for the preparation and characterization of La(OH)(3)/Fe3O4 magnetic nanoparticles were investigated and the scope and generality of the method was explored for a series of structurally diverse primary alcohols with electron-donating and electron-withdrawing groups. The best result was observed when 5mol% of La with respect to the benzyl alcohol was used at reflux condition under O-2 atmosphere. The La(OH)(3)/Fe3O4 magnetic nanoparticles could be easily isolated from the reaction mixture with an external magnet and reused at least 5 times without significant loss in activity.
