Summary
The reaction of furil (1) with trialkyl phosphites2 yielded caged phosphorane derivatives of types3a-c. Dry hydrogen chloride gas converted3a-c into the respectivea-hydroxyvinyl-phosphates8a-c which are equally produced by reacting furil with the appropriate dialkyl phosphite7. The reaction of furil with ylide-phosphoranes10 proceeded according to the Wittig reaction mechanism to give the respective ethylenes11a-c. The new compounds have been characterized by their spectroscopic data (IR, PMR,31P-NMR, MS) and elementary analyses.
Zusammenfassung
Die Reaktion von Furil (1) mit Trialkylphosphiten2 ergab Phosphoranderivate des Typs3a-c. Trockenes Chlorwasserstoffgas setzte3a-c zu den entsprechendena-Hydroxyvinyl-phosphaten8a-c um, die auch bei der Reaktion von Furil mit dem entsprechenden Dialkylphosphit7 entstehen. Die Reaktion der Ylid-Phosphorane10 verlief nach dem Mechanismus der Wittig-Reaktion und ergab die entsprechenden Ethylene11a-c. Die neuen Verbindungen wurden mittels spektroskopischer Daten (IR, PMR,31P-NMR, MS) und der Elementaranalysen charakterisiert.
