The nuclear magnetic resonance spectra ( 31 P, 19 F) of a variety of compounds containing phosphorus-fluorine bonds have been studied, in continuation of earlier investigations on the same type of compounds. The previously observed relationship between coordination number of phosphorus and δ P was generally confirmed, i. e. δ P becomes more positive as the coordination number around phosphorus increases. No meaningful substitution rules, either for chemical shifts or for P-F coupling constants, could be established. The data obtained are discussed qualitatively in relation to the electronegativity of the substituents and to the coordination number of phosphorus. Data on the preparation and characterization of numerous phosphorus-fluorine compounds are also included.
