Simple reaction procedure, economic and ecofriendly catalyst, mild reaction conditions and good to excellent yield of the products are the characteristic features of this study. The non-extractive workup/purification, economic and environmentally benign catalyst make this operationally straightforward procedure affordable for large scale.</p> ER -
