Abstract

Rf=: CH (CF,), variable-temperature lH NMR spectra showed that intramolecular ligand reorganization could be slowed on the NMR time scale. More recently Schmutzler and his coworkers4 have prepared a number of phosphoranes containing hexafluoroisopropoxy groups (OCH (CF3) 2= Ob). Compounds 2-5 are examples. Variable-temperature lgF NMR measurements were reported for compounds 3 and 5. Compound 3 showed two different ...
