Abstract

The cross-coupling reaction of arylboronic acid with chloroarenes to give biaryls was carried out in high yields at 70-80° C in the presence of a nickel (0) catalyst and K3PO4 (3 equiv) in dioxane or benzene. The nickel (0) catalyst in situ prepared from NiCl2⊙ L (L= dppf, 2PPh3)(3-10 mol%) and 4 equiv of BuLi at room temperature was recognized to be most effective. The reaction can be applicable to a wide range of chloroarenes having an ...
