摘要
The cross-coupling reaction of phenylboronic acid with chloroarenes to give biaryls was carried out in high yields at 80 degrees C in the presence of the nickel(0) catalyst and K3PO4 (3 equivs) in dioxane. The nickel(0) catalyst prepared in situ from NiCl2(dppf) (10 mol%) and four equivalents of BuLi was recognized to be most effective. The reaction can be applicable for a wide range of chloroarenes having an electron-withdrawing or an electron-donating group such as 4-CN-, 4-CHO, 2- or 4-CO(2)Me, 4-COMe, 4-NHAc, 3- or 4-Me, and 3- or 4-OMe, and 4-NH2.
