Significance

A magnetic Fe₃O₄@mesoporouspolyaniline core-shell nanocomposite (Fe₃O₄@mPANI) was prepared through the oxidative polymerization of aniline on PVP- and SDBS-substituted porous magnetic Fe₃O₄. Fe₃O₄@mPANI promoted the coupling of phenols and aryl chlorides to afford the corresponding diaryl ethers (23 examples, e.g. 3a-c, 53-99% yield) without deforming or aggregating of Fe₃O₄ nanoparticles.
