MINDO-forces calculations are performed, with complete optimization of geometries, on α-Xcyclopropylcations, where X is CF3 , CF2H, and CFH2. It was found that the fluorine atom interacts with the localized empty Pπ-type orbital on α-carbon atom and forms a bridge with an angle 57.1 degree. Calculations also are performed on CF3-cyclopropyl anion and CF2H-cyclopropenyl cation. The fluorine atom in CF3 and CF2H shows no such interaction with the a-carbon atom because there is no localized empty Prc-type orbital
