| Abstract: | An eco‐efficient one‐pot three component reaction between different aldehydes or ketones with alkynes and amines for the synthesis of propargylamines was performed using Fe3O4@TiO2/Cu2O as a nano‐magnetic composite under solvent free condition. The catalyst showed remarkable catalytic activity by decreasing the time of the reaction in comparison of other reported magnetic catalysts. In addition, the Fe3O4@TiO2/Cu2O can be easily recycled and reutilized for five times without apparent loss of catalytic activity. |
