The reaction between 4-thiaheptane-2,6-dione and 1,2-diaminobenzene in the presence of nickel(II) perchlorate results in the formation of a nickel(II) complex of a novel new heterotricyclic system: 1-methoxy-10-methyl-12-thia-2,9-diaza-tricyclo[8.3.1.03,8]tetradeca-3,5,7-triene, which on treatment with potassium cyanide gives 10-methy-12-thia-2,9-diaza-tricyclo[8.3.1.03,8]tetradeca-3,5,7-triene-1-carbonitrile, a case of metal-induced carbon–carbon bond formation.Key words: nickel-induced carbon–carbon bond formation, intramolecular cyclization, tricyclic formation.

Several hydroquinolyl alcohols and amines were electrochemically oxidized in methanol in the presence of sodium methoxide and potassium iodide to afford the corresponding intramolecular cyclization products. Furthermore, several amino malonates were electrochemically oxidized to yield the corresponding heterocyclic compounds through an intramolecular carbon–carbon bond formation in the presence of sodium cyanide in methanol.
