Functionalized arylcopper reagents react readily with alkenyl sulfonates in the presence of catalytic amounts of Fe(acac) 3 (10 mol%) providing the expected cross-coupling products in good yields. Ester or cyano group are tolerated. This cross-coupling can be performed with dienyl sulfonates leading to the corresponding substituted dienes.
在催化量的 Fe(acac) 3 (10 mol%) 存在下,官能化的芳基铜试剂很容易与烯基磺酸盐反应,以良好的产率提供预期的交叉偶联产物。允许使用酯或氰基。这种交叉偶联可以用二烯基磺酸盐进行,产生相应的取代二烯。
