Notes:
The He(I) photoelectron (PE) spectra of the diphosphacyclobutadienes 2 and 3 have been recorded. The interpretation of the first PE bands is based on SCF-MO calculations (MNDO method). It is found that the first two bands correspond to π-MOs which are mainly localized in the four-membered ring. The first two bands are shifted towards higher energy in the PE spectrum of 3; we ascribe this to an electron transfer from the four-membered ring in 3 to the phenyl substituents.
