Iron-based nanomaterials used as magnetic mesoporous nanocomposites to catalyze the preparation of N-sulfonylimines

A new magnetic nanocatalyzed synthetic method for the synthesis of aldimines was evidenced. The reaction was carried out in a Schlenk tube under reflux conditions using various solvents and different nanomaterials as catalysts. In these reactions, an excellent yield of aromatic aldimines was obtaine...

Summary:A new magnetic nanocatalyzed synthetic method for the synthesis of aldimines was evidenced. The reaction was carried out in a Schlenk tube under reflux conditions using various solvents and different nanomaterials as catalysts. In these reactions, an excellent yield of aromatic aldimines was obtained in the presence of silica-coated magnetic nanomaterials. The prepared catalyst was also characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, nitrogen adsorption and desorption studies, energy dispersive X-ray spectroscopy, and small-angle X-ray scattering spectroscopy. It was shown that the magnetic nanocatalysts can be easily separated from the reaction mixture using an external magnet and reused. [Display omitted]
