A ruthenium‐catalyzed carbonylative CH bond arylation process for the three‐component synthesis of complex aryl–(hetero)aryl ketones in an aqueous solution has been developed. By exploiting the ortho‐activating effect of nitrogen‐containing directing groups, a regioselective, successive twofold C(sp2)C(sp2) bond formation has been achieved. This straightforward catalytic process provides access to
甲钌催化carbonylativeÇ 复杂芳基- (杂)的三组分合成芳基酮在水溶液中H键的芳基化过程已经被开发出来。通过利用邻-activating含氮定位基团,一个区域选择性的作用,逐次双重C(SP 2) C(SP 2)键形成已经实现。这种直接的催化方法提供了访问多功能产品中多种生物活性化合物盛行和用于随后的转化提供了一个有价值的官能团。
