The full potential of a high valent metal chloride as both a chlorinating and an oxidative agent was explored by allowing WCl6 to react with N-(2,6-diisopropylphenyl) alpha-diimines, in CH2Cl2 at room temperature. These a-diimines underwent unprecedented conversion to quinoxalinium cations via intramolecular C-N coupling.
