Abstract In this study, a novel, heterogeneous and reusable catalyst prepared by the coordinative anchoring of metal(II) phthalocyanine complexes (M: Fe, Cu) on the guanidine-functionalized magnetic nanoparticles was reported. The synthesized catalysts were characterized by scanning electron microscopy (SEM), powder X-ray diffraction (XRD), vibrating sample magnetometer (VSM), thermal gravimetric analysis

Abstract Silica‐supportedsodiumhydrogensulfate (NaHSO4 · SiO2) efficiently catalyzes the four‐component reaction of aryl aldehydes, enolisable ketones, acetyl chloride, and acetonitrile to form the corresponding β‐acetylamino ketones at room temperature. The catalyst is inexpensive and ecofriendly and works under heterogeneous conditions.The present methodology offers several advantages such as
