Nature of Electron Donor Centers of Phosphoalkenes in H-Bond Complexes

Abstract

Phosphoalkenes (1), (R, R^I, and R^II = H, Hal, Nalk₂) show alternative nucleophilic properties towards HX acids or transition metal salts, and depending upon reagent characteristics form addition products throught one of P=C double bond atoms. Coordination of a ligand to a cation by its π-electron donor is also observed due to quazidegeneration of higher occupied molecular orbital.
