The Ni-catalyzed reaction of ortho-phenoxy-substituted aromatic amides with alkynes in the presence of LiOtBu as a base results in C–O/N–H annulation with the formation of 1(2H)-isoquinolinones. The use of a base is essential for the reaction to proceed. The reaction proceeds, even in the absence of a ligand, and under mild reaction conditions (40 °C).

在 LiO t Bu 作为碱存在下, Ni 催化的邻苯氧基取代的芳族酰胺与
炔烃的反应导致 C-O/N-H 环化,形成 1( 2H )-
异喹啉酮。碱的使用对于反应进行是必不可少的。即使在没有
配体的情况下,在温和的反应条件(40°C)下,反应也会继续进行。芳环上的给电子基团促进反应。该反应也适用于
氨基甲酸酯(C-O 键活化)、甲
硫基(C-S 键活化)和
氰基(C-CN 键活化)作为离去基团。
