A series of new dicyanopyrazine-related heterocycles such as quinoxalines, furopyrazines and pyrrolopyrazines were synthesized from diaminomaleonitrile.Their dicyanopyrazine moieties can also be converted to pyrazinoporphyrazines.The Wittig reaction of 2,3-bis(bromomethyl)-5,6-dicyanopyrazine and the ring-closure reactions of 2,3-dichloro-5,6-dicyanopyrazine were useful methodologies to extend the ? - conjugation giving new heterocycles.The absorption and fluorescence spectra of new compounds were correlated with their chemical structures.
