The electron deficient center (carbonium ions or other cations) at the β-position from a metal in organometallic compounds is stabilized by a hyperconjugation (σ-π conjugation) which has shown a very large resonance effect. Such a conjugative delocalization of neighboring σ bonds is available without changing the reactant geometry and is termed “vertical stabilization”. Furthermore this is completely separated from the electron-donating inductive effect by means of the demonstration of stereo electronic requirements. The effects of structural changes on the magnitude of the vertical σ-π conjugation are also discussed in details.
