The silyl ethers C6H5OSi(CH3)3 and C6F5OSi(CH3)3 undergo silicon-oxygen bond cleavage reactions with fluorophosphoranes, RnPF5-n (n = 0, 1, 2; R = CH3, C6H5, (CH3)2N in the case of C6H5OSi(CH3)3; n = 0, 1, 2; R = CH3, C6H5 in the case of C6F5OSi(CH3)3), to give a series of thermally stable compounds of the types (C6H5O)3-nPRnF2 and (C6F5O)3-nPRnF2 (n = 0, 1, 2). The intermediate (RO)2PF3, assumed in the reactions of PF5 with ArOSi(CH3)3, was isolated only in the form of the isomeric stable phosphonium salt [(RO)4P] [PF6]. The 31P and 19F nmr spectra of the new compounds are reported and discussed in terms of the structures of the molecules.
