Abstract: | Schmidt reaction of arylaldehydes, ketones and aromatic carboxylic acids using task-specific ionic liquid, bmim]N3 in the presence of AcOH/H2SO4 proceeds at 50–60 °C within 2–4 h to give the corresponding products. Benzaldehydes containing electron releasing groups afforded to the related benzamide derivatives. Benzonitrile derivatives were formed from the reaction of benzaldehydes containing electron withdrawing groups under these conditions. High yields of the related amides and anilines were obtained from the reaction of a variety of ketones and aromatic carboxylic acids, respectively, utilizing this procedure. |
