Synthese und Strukturanalyse von 1,2,3,4‐Tetrahydrobenzo[g]chinoxalin‐5,10‐chinonen

Abstract: Im Rahmen unserer Untersuchungen uber Komplexe aus paramagnetischen Azomethinliganden und diamagnetischen Schwermetall-Ionen I' haben wir versucht, als 4-zahnige Liganden Bis-benzyliden-2,3-diamino-l,4-naphthohydrochinone aus 2,3-Diamino-1,4-naphthohydrochinon und verschiedenen o-funktionalisierten Benzaldehyden, analog bekannter Bis-benzyIiden-o-phenylendiamine*~", zu synthetisieren.Die Massenspektren der so gewonnenen tiefblauen Produkte sind mit den Zielverbindungen vereinbar. Im Gegensatz dazu stehen die E… Show more
