Fluorophosphoranes containing the perfluoropinacolyl ring system. Part III. Carbon-13 nuclear magnetic resonance studies
Abstract
The 13C n.m.r. spectra of fluorophosphoranes containing the perfluoropinacolyl (pfp) ring system are reported: PRF2(pfp)[R = F, Me, But, Ph, NEt2, or N(SiMe3)2] and N2(SiMe3)2P2F2(pfp)2. The results are consistent with previously reported 19F n.m.r. studies and give evidence for a two-stage intramolecular exchange process.
