Abstract

Charge Distribution and Reactivity of Phosphorous-organic Campounds, XIII). The n-Electron Structure, Dipole Moments and Electron Spectra of Fluorenone-(9/-arylphosphazines 2 )Several MO diagrams and energy levels, calculated by the H uckel-MO-method (HMO), are presented for the model molecule fluorenone-(9)-phenylphosphazine. Especially the dependence of the x-electron structure of the model on the resonance integrals PPN and Ppc has been examined. In addition the dipole moments and the UV-spectra of a series of p-substituted fluorenone-(9)-aryldipropyl-and -aryldiphenylphosphazines have been discussed. The model is employed qualitatively for these experimental results. Bei den Verbindungen des Typs 21) und 35) gelang mit einem einfachen ,,ZweiLiganden-HMO-Modell" eine qualitative Deutung der experimentellen Befunde,
