The reactions were administered underneath Solvent-free conditions. The current methodology offers many benefits like good yields, easy procedure, simple work-up and ecofriendly reaction condition. The catalyst is well ready, stable and economical underneath the reaction conditions. %U http://www.ajchem-a.com/article_78187_7edc753e802565c97e7fd25f0e76b191.pdf
