Synthesis of organosilyl compounds-containing 1,2,4,5-tetraaryl imidazoles sonocatalyzed by M/SAPO-34 (M: Fe, Co, Mn, and Cu) nanostructures

The one-step synthesis of 1,2,4,5-tetraaryl imidazoles by use of a series of M/SAPO-34 (M: Fe, Co, Mn, and Cu) nanocatalysts was described. Cu/SAPO-34 catalyst had the highest activity in improving the efficiency of the heterogeneous cyclo-condensation of an aldehyde, benzil, ammonium acetate and a primary aromatic amine in water under ultrasonic irradiation. Some imidazole derivatives were studied for synthesis of a series of new, multi-substituted imidazoles containing organosilyl groups including carbosilanes (Si-C) and siloxanes (Si-O).
