DUNACH, E. et al. Electrochemical Study of Nickel (salen) and Cobalt (salen) Derivative Complexes in the Presence of Unsaturated Halides. Port. Electrochim. Acta [online]. 2003, vol.21, n.2, pp.191-196. ISSN 0872-1904.

The electrochemical intramolecular cyclisation of allyl 2-bromophenyl ethers in N,N'-dimethylformamide at constant current in a diaphragmless cell has been developed using Ni(II) and Co(II) complexes as electron-transfer mediators. Cyclic compounds are obtained in good yields under appropriate experimental conditions.

Palavras-chave : electron transfer; cyclisation; nickel; cobalt; radicals; heterocycles.
