Notes:
The nuclear magnetic resonance signals exhibited by the ipso-carbon atoms of a variety of phenylated phosphorus compounds were found to span over the remarkably wide range of + 162 to + 117 ppm. Nevertheless, these changes in chemical shifts have little diagnostic value. They are tentatively attributed to a charge-mediated contraction and expansion of the C,P σ-bond orbital on one hand and to a σ-bond induced deformation of the aromatic π-electron cloud on the other.
