A new magnetic nanoparticle-supported catalyst for Clauson-Kaas reaction. The corresponding N-substituted pyrroles in by magnetic separation and recycled for antimony catalyst was prepared and evaluated as a recoverable reaction proceeds efficiently in aqueous medium to give the high yield. The immobilized catalyst could be easily recovered six times without significant loss of its catalytic activity. (c) 2013 Elsevier B.V. All rights reserved.
