Abstract

Abstract 2H-Thiopyran-Derivate liefern durch Pyrolyse bei 240-260 C Thiophene. Einflüsse von Substitutionen in 3-bis 6-Stellung der 2H-Thiopyrane auf diese neuen thermischen Umlagerungs-und Fragmentierungsreaktionen sowie mechanistische Vorstellungen darüber werden ausführlich diskutiert. Unsere Ergebnisse beschreiben ein neues, dreistufiges Synthesekonzept für Thiophene aus Carbonylverbindungen über ...
