摘要：

In order to explain the reactivity of aryldihalophosphites towards halophosphonium salts, photoelectron spectra of PhOPX(2) (X=F, Cl) were studied. Electron densities of boundary molecular orbitals (MO) for these compounds were calculated using the MNDO method and analyzed. Replacement of F by Cl was shown to substantially affect the sigma orbital. When X=Cl, this MO embraces the whole of the OPX(2) moiety whereas for X=F it is localized on the P-O bond.
