Alkyl radical hyperconjugation in phosphorus compounds

Conclusions The³¹P and¹⁹F chemical shifts in phosphorus compounds of various conformations vary with the number of hydrogen or fluorine atoms attached to the-C atom of the phosphorus atom alkyl or perfluoroalkyl radical. This effect can be explained in terms of alkyl radical hyperconjugation.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 11, pp. 2435–2439, September, 1976.
