Institute of Organic Chemistry, Academy of Sciences of the Ukrainian SSR, Kiev aut Role of multiple bonds of tetracoordinated phosphorus atom in the magnetic shielding of its nucleus [Elektronische Daten] [A. Tarasevich] On the basis of a previously proposed approach to investigation of the nature of the chemical shift σ31P, it has been shown that the dependence of shielding of the 31P nucleus on the multiplicity of one of the bonds (PM) of the phosphorus atom in the molecule is not monotonic over the entire interval of variation of the corresponding parameter γPM. When γPM is smaller than a certain value γ0, which is determined by the difference between interactions of the P atom with the atom in question (M) and other substituents, the dependence of 31P nuclear shielding on γPM should be antibatic, and when γPM > γ0 symbatic.
