Electron Deficient Compounds. II. Relative Energies of ``Half‐Bonds''

摘要: It is suggested that the tendency to make use of all low energy orbitals underlying principle electron‐deficient bonding. Simple theoretical arguments, limited special case two electrons and three orbitals, are given show this a direct consequence quantum‐mechanical theories valence.Two half‐bonds shown be lower than single bond plus an unused orbital in most cases. The form should important symmetrical cases, particularly where electronegativities atoms involved equal, e.g., boron hydrides H3+.Certain consequences proposal fields organo‐metallic compounds, catalysis, molecular rearrangements pointed out. at temperatures complexes may exist between molecules with excess no unshared pairs.
