A convenient and excellent yield procedure for the preparation of benzylidenemalononitrile by addition-elimination reaction of imine with malonitrile in the presence of immobilized H3PW12O40 as heterogeneous catalyst in water is described, and a variety of the corresponding products were obtained in high yield (up to 99%). The approach was characterized by simple operation, environment friendly, excellent yields and the catalyst was found to exhibit better recyclability. It provides a new method for the carbon-carbon bond formation in organic synthesis.
