A nanomagnetic triazole-based Schiff-base complex of palladium(0) as an efficient heterogeneous catalyst for the Mizoroki–Heck C–C cross-coupling reaction under green conditions

Year: 2025

Type: article

Abstract: reduction to Pd(0) afforded a stable, magnetically separable catalyst. Comprehensive characterization (FT-IR, XRD, TGA, EDX, ICP-OES, WDX, FE-SEM, TEM, and VSM) confirmed its successful synthesis. The catalyst demonstrated outstanding activity in the Mizoroki-Heck C-C cross-coupling reaction, resulting in efficient coupling of a diverse range of aryl iodides, bromides, and chlorides with butyl acrylate in PEG-400 as a green solvent and co-catalyst. It exhibited superior selectivity for aryl iodides and bromides and maintained high efficiency over eight consecutive cycles with minimal metal leaching. The use of cost-effective materials, facile magnetic recovery, and scalability make this catalyst an eco-friendly and economically viable alternative to conventional palladium-based methodologies.
