摘要

1,3,2-diazaphospholenes and related compounds can formally be regarded as complexes of phosphinidenes (R-P) with 1,4-diazabutadienes. The dissociation Gibbs free energies of these "complexes" were calculated by using density functional theory (B3LYP/3-21G(*) and B3LYP/6-311+G**). The dissociation Gibbs free energies show systematic dependence on the phosphorus substituent as well as on the stability of the N-donor ligand formed as a byproduct. The thermodynamics and kinetics of the dissociations were thoroughly examined. The results allow us to conclude that novel routes of phosphinidene generation can be developed.
