In the presence of [RhCp∗Cl2]2, N-pivaloyl anilines react with internal alkynes to give the corresponding 2-alkenylpivalimides under redox neutral conditions through C-H activation. This redox neutral hydroarylation, which does not require an external organic acid, unlocks a regioselective synthetic route to 2-alkenyl anilines and is generally applicable to diversely substituted electron rich and electron
在[RhCp * Cl 2 ] 2的存在下,N-新戊酰基苯胺与内部炔烃反应,在中性氧化还原条件下通过CH活化得到相应的2-烯基新戊酰亚胺。这种不需要外部有机酸的氧化还原中性加氢芳基化反应,可以解开向2-烯基苯胺的区域选择性合成路线,通常适用于各种取代的富电子和贫电子新戊二酰亚胺。
