Abstract
|
Magnetic Fe(OH)3@Fe3O4 nanoparticles were successfully prepared and
characterized. This magnetic nanocomposite was employed as an efficient, reusable, and
environmentally benign heterogeneous catalyst for the direct amidation of alcohols with
amine hydrochloride salts. Several derivatives of primary, secondary and tertiary amides were synthesized in moderate to good yields in the presence of this catalytic system. The catalyst was successfully recycled and reused up to six times without significant loss of its
catalytic activity.
