摘要

This comprehensive review highlights copper on magnetic nanoparticle (MNP) catalysts as a pivotal advancement in the synthesis of 1,2,3-triazoles, underscoring their versatility and green chemistry advantages. It traces how magnetic supports—predominantly Fe₃O₄-based cores—stabilize copper species, enhance catalytic efficiency, and enable straightforward post-reaction separation, thereby facilitating reuse and minimizing metal contamination in products. By surveying literature from 2015 through 2025, the work details the design and functionalization of magnetic substrates, the integration and stabilization of copper nanomaterials, and a spectrum of 1,3-dipolar cycloaddition protocols that efficiently yield 1,2,3-triazoles. Beyond practical performance—characterized by fast reaction rates and high selectivity—the review also delves into mechanistic insights, including how magnetic fields may influence catalytic behavior, thereby offering a nuanced understanding of activity trends. Collectively, the discussion presents a cohesive narrative of how copper-anchored magnetic nanocatalysts embody sustainable, reusable, and scalable solutions for triazole synthesis, reinforcing their potential to drive future innovations in catalysis and heterocyclic chemistry.
