Relationship between the photoelectron spectra and torsional barriers of aminophosphines
Abstract
The trends in the nitrogen and phosphorus lone-pair ionization potentials of Me2NP(CF3)2(1), Me2NP(Cl)CF3, (2), and Me2NPCl2(3) suggest that the P–N torsional barriers in aminophosphines arise predominantly from steric and lone pair–lone pair repulsion effects.
