Abstract

P, P-triphenylphospha-X5-azenes 2233 where we examined the 31P, 13C, and 15N NMR spectra, oxidation, and reduction by cyclic voltammetry (CV) and carried out PRDDO molecular orbital calculations. The observations were, in general, explained by inductive and resonance effects and were aided and reinforced by the calculations. The observed correlations between experimentally measured parameters and Hammett substituent ...
