Abstract

Abstract Stabile Phosphinalkylene der Struktur R [BOND] CO [BOND] CR 1 [DOUBLE BOND] P (C 6 H 5) 3 (7) können mit wäßriger NaJO 4-Lösung zu α. β- Dicarbonylverbindungen 8 oxydiert werden. Phosphoniumperjodate [R-CH 2-P⊖(C 6 H 5) 3] JO 4⊖(15) ergeben beim Behandeln mit Basen Olefine R [BOND] CH [DOUBLE BOND] CH [BOND] R (2) Aus Bis-phosphoniumperjodaten lassen sich auf diesem Wege unter ...
