Magnetic g-C3N4 nanocomposite-catalyzed environmentally benign aminolysis of epoxide

摘要

A magnetic graphitic carbon nitride (g-C3N4) nanocomposite was prepared and used as a novel magnetically retrievable nanocatalyst for efficient ring opening of epoxides with aromatic amines. A variety of aryl and alkyl epoxides were examined under the mild reaction condition and the corresponding beta-amino alcohols were obtained in good to excellent yields under solvent-free condition. Using the Fe3O4 as a low-priced magnetic support to immobilize an active material g-C3N4 can provide a better result than using traditional catalysts with respect to the efficiency, yield, easy work-up, short reaction time, possibility of regeneration, and ease of applicability .
