system was developed as a catalyst for the Knoevenagel condensation and Knoevenagel initiated three-componentone-potsynthesis of 4H-pyrans at room temperature with high yields and in short reaction times. Further, the EDDF-PEG600 catalytic system was recycled six times without any appreciable loss in its activity and hence can be termed as a green, environmentally benign catalytic system. A plausible
