Nickel embedded on triazole-modified magnetic nanoparticles: A novel and sustainable heterogeneous catalyst for Hiyama reaction in fluoride-free condition

An interesting MNPs -supported nano-nickel catalyst was successfully synthesized through â??clickâ? reaction of azide-functionalized magnetic nanoparticles with 2-ethynylpyridine followed by immobilization of nickel nanoparticles. In deed, the azide group was introduced into the magnetic nanoparticles surface via ring-opening of exist oxirane rings on the surface. The catalytic activity of this catalyst was then evaluated for Hiyama cross-coupling reaction under fluoride-free conditions. Besides, the as-prepared nanocatalyst can be reused easily by an external magnet for several times.
