Magnetic sodium aluminate 60 wt.% as an efficient and recyclable catalyst for the Rap–Stoermer reaction

Abstract Synthesis of 2-aroylbenzofuran derivatives through Rap–Stoermer reaction with condensation of salicylaldehydes and substituted phenacyl bromides in the presence of magnetic sodium aluminate 60 wt.% (MNPs-60). The catalyst can be easily recovered from the reaction mixture by applying an external magnetic field. This catalyst is stable and can be reused multiple times without losing its catalytic properties. High yields of product in a short experimental time and easy workup are other advantages of the present method.
