electrochemistry and mediated by nickel catalysis is described. This domino process transforms various aryl halides bearing a propargyl chain into substituted heterocycles in one single operation, with high stereoselectivities and in good to high yields. This reaction, characterized by a cyclic voltammetry set of experiments, proceeds following a syn-exo-dig cyclization process. When run at 80 °C, vinylbenzofuranes
描述了由电化学促进并由镍催化介导的三键的分子内碳金属化。这种多米诺方法在一次操作中将带有炔丙基链的各种芳基卤化物转化为取代的杂环,具有高立体选择性和高产率。该反应以循环伏安法为特征,按照合成-外-挖环化过程进行。当在 80 °C 下运行时,可以获得适合环加成反应底物的乙烯基苯并呋喃。
