Recent Advances in Iron Nanoparticle‐Catalyzed Approaches to Pyrazole Scaffolds Syntheses

ABSTRACT The concept of a green catalyst is in high demand for the perspectives of green synthesis. Specifically, Fe‐based nanoparticles have gained more attention in recent years owing to the various novel features. Over the past decade, Fe‐based nanoparticles have been exploited extensively in the process of organic synthesis. Among organic frameworks, pyrazole and its scaffolds are acknowledged as a preferred structure, as they provide a promising area for the identification of lead structures for drug‐discovery programs. Fe‐based nanoparticles serve as green catalysts in the synthesis of pyrazole and its derivatives. This review paper presents the first summarization of Fe‐based nanoparticle‐catalyzed synthesis of pyrazole‐based molecular structures, marking a novel contribution to the literature.
