Allowing the direct interaction of: N -aryl α-diimines with a high valent metal chloride: One-pot WCl6-promoted formation of quinoxalinium salts

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) α-diimines, in CH2Cl2 at room temperature. These α-diimines underwent unprecedented conversion to quinoxalinium cations via intramolecular C–N couplin
