N2 - Potassium-graphite intercalate C8K is the reagent of choice for the ring closure of the dianions of 2, 3-diarylquinoxalines derhatives 1-3 to the dianions of dibcnzo[a, c]phenazine derivatives 4-6 in high yields and high degree of purity, this process appears to occur via a thermal electrocyclic process of the dianions. Potassium-graphite intercalate, C8K, is a useful and efficient reducing agent.1-3 Its highly ordered structure, combined with high reactivity, enables selective reduction processes such as reductive dimerization of ketones4 and stereospecific debromination.5
