Reductive cyclizations using environmentally friendly electrochemical methodologies

摘要

The electrochemical reductive cyclization of unsaturated organic halides was examined in the presence of Ni(II) complexes associated to macrocyclic ligands. Ni(0) or Ni(I) intermediate species were obtained according to the nature of the ligand. The reactions could be carried out in protic solvents such as ethanol, buthanol or ethanol-water mixtures and still be catalytic and highly efficient.
