Magnetic Pd-Nanoparticles catalyzes a one-pot diazotization-cross-coupling reaction of anilines and arylboronic acids to yield biaryls in good to excellent yields. The catalyst can recovered through magnetic separation and reused for three times. There were several obvious advantages such as broad applicability, high selectivity, simply experimental operation as well as the convenient preparation, high efficiency and reusability of catalyst.
