An intramolecular carbometallation of a triple bond promoted by 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 that are suitable substrates for cycloaddition reactions are obtained.

supporting information; experimental part, p. 4753 - 4755 (2010/01/15)
Reaction of Ni(0) in the presence of iodoarylethers 1 leads, after syn intramolecular carbonickelation of the triple bond, to nucleophilic vinylnickels which can be trapped, in a tandem process, by various electrophiles introduced at the onset of the reac
