Abstract

The cross-coupling reaction of arylboronic acids (1.3 equivs) with aryl methane-sulfonates was carried out in the presence of a nickel (0) catalyst (3 mol%) and K3PO4· nH2O (3 equivs). The use of toluene as the solvent and the nickel (0)-dppf catalyst prepared from NiCl2 (dppf) plus dppf with BuLi were recognized to be the most efficient to achieve both high yields and high selectivity. The reaction can be applied to various electron-deficient ...
