POLARITY AND POLARIZABILITY PARAMETER DETERMINATIONS IN COMPOUNDS CONTAINING A P[sbnd]N BOND

Abstract

The dipole moments and polarizability ellipsoids of phosphorus-containing bonds in 2,6,7-trimethyl-4-methyl-2,6,7-triaza-1-phosphaicyclo[2.2.2]octane (3) and its 1-oxide (4) and 1-sulfide (5) and in 2-dimethylamino-1,3,2-dioxaphosphorinane (2) have been determined from dipole moment, Kerr effect and depolarization of Rayleigh scattering measurements. The conformational rigidity of bicyclic compounds such as (3–5) as well as of several 2-oxo-2R-4,6-dimethyl-1,3,2-dioxaphosphorinanes are utilized in considering the implications of assuming that the component moments are primarily directed along the phosphoryl bond.
