Flash vacuum thermolysis (FVT) of cyclic phosphine-borane complexes and direct analysis of the gaseous flow by ultraviolet photoelectron spectroscopy allowed us to characterize transient phosphinoboranes and to provide information about their electronic properties. This study was also supported by HRMS results. Ab initio calculations with the hybrid " functional B3LYP and the basis set 6-311G (d, p) allowed us to assign the different ionizations of the PE spectra and provided more information about the character of the BP bond. © 2001 American Chemical Society.
