O-SILYLATION OF SOME UNSATURATED CYCLIC PHOSPHINE OXIDES

The phosphoryl oxygen of 1.6-dihydrophosphinine oxides is silylated rapidly at room temperature by bis(trimethylsilyl)trifluoroacetamide; the product loses a ring proton to establish the resonance stabilized γ 5 -phosphinine ring system. Similar events take place with a 3-keto derivative of a tetrah...
