Abstract
The vaporization enthalpies (Delta H-vap) of 97 primary, secondary, and ter tiary alkylphosphines and alkyl(aryl)phosphines with different spatial stru ctures were calculated using the Trouton and Wadso equations and the first- order topological solvation index (l)chi(S). The contributions of the H2P a nd HP groups and the phosphorus atom to the vaporization enthalpies of prim ary, secondary, and tertiary phosphines, respectively, were calculated. The results obtained can be used in calculations of Delta H-vap for related ph osphorus compounds.
