摘要: We report here the first dendritic phosphine-stabilized nickel nanoparticles, which can be prepared from nickel(II) chloride, a third generation phosphine dendrimer and surfactant tetraoctylammonium bromide (TOABr) by two-phase reduction using sodium borohydride. The resulting nanoparticles are found to highly active recyclable catalyst for Suzuki coupling reactions, especially those extended aryl chloride substrates, affording biaryls in moderate good yields.
