PbO nanoparticles were found to be highly efficient, eco-friendly and recyclable heterogeneous catalyst. PbO nanoparticles were prepared by hydrothermal method and characterized by IR, XRD, BET Surface area, SEM, EDAX and TEM with SAED techniques. Graphical Abstract One-pot synthesis of tetrahydro benzo pyrans and benzylidene malonitriles using PbO nanoparticle under solvent-free condition at room temperature has been presented. PbO nanoparticles were found to be highly efficient, ecofriendly and recyclable catalyst.
