ChemInform Abstract: Application of Photoelectron Spectroscopy to Molecular Properties. Part 34. Phosphaethene. Synthesis by Vacuum Gas‐Solid Reaction (VGSR) and Characterization by Photoelectron Spectroscopy.

Abstract

For the first time the electronic structure of phosphaethene (CH2=PH), the unstable parent compound in the phosphaalkene series, is deduced from its photoelectron spectrum.

Density Functional Theory Study of the Electronic State, Geometry, and Harmonic Frequencies for Linear CnP2 Clusters: A Comparison with CnN2

“…In terms of the electronic structure of the heteroatomcontaining molecules, a comparison of imine (CH 2 NH) and phosphaethylene (CH 2 PH) indicates that the HOMO of the former is the lone pair, while that of the latter corresponds to the π-bond. 16,18 It has also been shown 16 that phosphaalkynes (R-CtP) and nitriles (R-CtN) differ in bond polarity because of the electronegativity difference noted above. The ionization energy of the phosphaalkynes is reported in the same work to be much lower than that of the nitriles.…”
