construction of heterocycles. This is ideally catalyzed by earth-abundant and eco-friendly transition metals. We report Co(III)-catalyzed redox-neutral coupling between arenes and alkynes using an NH amide as an electrophilic directing group. The redox-neutral C–H activation/coupling afforded quinolines with water as the sole byproduct.
由双官能团引导的C–H活化使杂环的构建成为可能。理想的情况是,富含地球的,环保的过渡
金属可以催化这种反应。我们报告使用NH酰胺作为亲电导向基团的Co(III)催化的
