The cross-coupling reaction of arylboronicacids (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
在镍(0)催化剂(3摩尔%)和K 3 PO 4 ·nH 2 O(3当量)的存在下,进行芳基硼酸(1.3当量)与芳基甲烷磺酸盐的交叉偶联反应。公认使用甲苯作为溶剂以及由NiCl 2(dppf)加dppf与BuLi制备的镍(0)-dppf催化剂是实现高收率和高选择性的最有效方法。该反应可用于各种电子不足和富集的芳基甲磺酸盐,以得到高产率。
