Cw. Allen et Sd. Worley, Organophosphazenes. 24. Ultraviolet photoelectron spectra of selected alkenyl- and alkynylfluorocyclotriphosphazenes, INORG CHEM, 38(22), 1999, pp. 5187
The valence shell ionization energies of a series of alkenyl- and alkynylfl
uorocyclotriphosphazenes have been determined using ultraviolet photoelectr
on spectroscopy. In the alkenylphosphazene series, the effect of substituen
t variation on both the olefin and the cyclophosphazene ring have been exam
ined. The data have been consistently interpreted in terms of a model in wh
ich phosphazene substituent effects are exclusively transmitted through pol
arization of the endo- and exocyclic sigma bonds.
