摘要
Nano-MgO a basic catalyst was prepared by solution combustion technique. It was characterized by powder XRD, SEM, BET and TEM analyses. It was used as a catalyst for the study of microwave-assisted N-formylation of various aromatic and alkyl amines with formic acid under solvent-free conditions. Nano-MgO showed excellent catalytic properties and the reactions went to completion, within 1-2 min to give products in high yield (90-98%). The catalyst is recoverable quantitatively and re-cycled with almost consistent activity. This new nano catalyst has the advantages of higher yield, lower cost, reduced environmental hazards, and the procedure is highly convenient.
