摘要

Abstract Unsymmetrical metal-free and zinc complexes of pyrazino-quinoxalino- porphyrazines (PQP) bearing eight diethylamino groups have been synthesized by statistical tetramerization of 2, 3-bis (diethylamino) quinoxaline-6, 7-dicarbonitrile and 5, 6- bis (diethylamino) pyrazine-2, 3-dicarbonitrile in lithium butanolate. For this purpose, a new heteroatom-substituted quinoxaline precursor, 2, 3-dichloro-6, 7-dicarbonitrile, was ...
