Preparation of Hierarchically Structured Perlite NPs/Metformin-Co (II) System to Catalyze the Green Synthesis of Pyrazolopyranopyrimidines.
This study presents an innovative heterogeneous nanocatalytic system designed through a multistep synthetic approach involving the surface functionalization of perlite nanoparticles (Perlite NPs/Met-Co(II)). Comprehensive characterization using fourier transform infrared spectroscopy (FTIR), X-ray diffraction, field-emission scanning electron microscopy, energy-dispersive X-ray analysis (EDX), elemental mapping, thermogravimetric analysis, and brunauer-emmett-teller (BET) analyses confirms the successful formation of a hierarchically structured catalyst. The catalyst enables efficient one-pot multicomponent synthesis of pyrazolopyranopyrimidines in water (100 °C, 5 mg loading), yielding 87-95% in 30-60 min. The presented method adhering to green principles and also recyclability (6 cycles) and synergistic performance provides an atom-economic platform for sustainable heterocycle synthesis.
期刊介绍：
ChemistryOpen is a multidisciplinary, gold-road open-access, international forum for the publication of outstanding Reviews, Full Papers, and Communications from all areas of chemistry and related fields. It is co-owned by 16 continental European Chemical Societies, who have banded together in the alliance called ChemPubSoc Europe for the purpose of publishing high-quality journals in the field of chemistry and its border disciplines. As some of the governments of the countries represented in ChemPubSoc Europe have strongly recommended that the research conducted with their funding is freely accessible for all readers (Open Access), ChemPubSoc Europe was concerned that no journal for which the ethical standards were monitored by a chemical society was available for such papers. ChemistryOpen fills this gap.
