摘要：

Methylene protons of benzyl groups in dibenzyl 2-pyrridylphosphate show strong magnetic non-equivalence in CDCl3, while the effect is absent in benzene-d(6) solutions. The non-equivalence is explained by the intramolecular N --> P interactions leading to the ''quasi trigonal bipyramidal'' geometry of the substrate, observed in solid state, as determined by X-ray diffraction.
