31P-NMR Investigation of N-Aryl-substituted Iminotriphenylphosphoranes: Hammett Relationship between 31P Chemical Shift and Substituent ConstantsThe 31P chemical shifts of p- and m-substituted N-arylimino-triphenylphosphoranes reflect the electronic influence of the substituents and can be correlated by a Hammett relationship. This new correlation was used for the estimation of σ- resp. σ-values for p-(CH3)2N-, p-C6H5CO- and p-C6H5—N = N-groups as well as for β-naphthyl- and pyridyl(4)-rings. The applicability of a similar Hammett equation for the o-substituted compounds is not possible.
