Abstract
The reaction of 2,2-dimethyl-(1,8-naphtho[c,d])-1,3,2-dioxysilenin (3) and 2,2-dimethyldibenzo-1,3,2-dioxysilepin (4) with (C6H5)2PF3 gave the expected monocyclic fluorophosphoranes. Reaction of the same siloxy compounds with PF5 gave products which could not be purified but whose 19F nmr spectra suggested that the desired spirocyclic compounds were present in the impure products. Reaction of the siloxy compounds with C6H5PF4 did not yield identifiable products. The 19F nmr spectra of the products obtained are discussed and structures are tentatively assigned.Keywords
