For the first time quantum-chemical calculation of a molecule of phenylcyclopropane is executed by the method modified neglect of diatomic overlap (MNDO) with optimization of geometry on all parameters. The optimized geometrical and electronic structure of this compound is received. The acid power of phenylcyclopropane is theoretically appreciated. It is established, than it relate to a class of very weak H-acids (pKa = +33, where, pKa-–universal index of acidity).
