Summary: Core/shell CaO@SiO2-SO3H nanoparticles were prepared by stabilizing sulfonic acid on the surface of silica-coated CaO nanoparticles. The catalyst was used for the green synthesis of dihydropyrano[2,3-c]pyrazoles and tetrahydrobenzo[b]pyrans with good to excellent yields. It could be recycled and reused for six runs without significant loss of activity.
