ABSTRACT
Quantum-chemical calculation of molecules of α-cyclopropyl-p-izopropylstyrene, α-cyclopropyl-2,4-dimethylstyrene, α-cyclopropyl-p-ftorstyrene was done by method MNDO. Optimized by all parameters geometric and electronic structures of these compound was received. The universal factor of acidity was calculated (pKa = 32). Molecules of α-cyclopropyl-p-izopropylstyrene, α-cyclopropyl-2,4-dimethylstyrene, α-cyclopropyl-p-ftorstyrene pertain to class of very weak Н-acids (рKа > 14).
