    The σ-bonds geminal to the π-reacting center have been proposed to participate in the organic reactions via the cyclic transition states and to control the reactivity and the selectivity. An electron-donating geminal σ bond at the Z position enhances the reactivity of the olefins. An electron-donating σ bond prefers the Z position of the π bond in the products of the reverse reactions. The effects of the geminal bond participation come from the orbital phase properties of the cyclic interactions including the geminal σ bonds.
