Abstract
Abstract An efficient procedure for Knoevenagel condensation of araldehydes with malononitrile has been developed using a mixture of environmentally friendly nano MgO and commercial MgCl2 as catalyst. The reactions were carried out at 25 C using grindstone technique. The protocol developed is advantageous as it follows the green-chemistry norms avoiding the use of any organic solvent and affording excellent yield of the products.
