Reactions of Fluorophosphoranes with Trimethylsilyl (Trimethylsilyloxy)acetate: Structures, NMR-Spectroscopic Studies and X-ray Investigations of Mono- and Spirocyclic (Acyloxy)phosphoranes

The reaction of the tetrafluorophosphoranes RPF4 (R = Me, Ph) with trimethylsilyl (trimethylsilyloxy)acetate (1) yields the corresponding monocyclic fluoro(acyloxy)phosphoranes 2 and 3 by cleavage of the Si-O bond and elimination of (CH3)3SiF. 2 and 3 wer
