Quantum-chemical calculations by a method of Hartrii-Focka with parametres UHF and RHF frames 4-replaced 2,6-di-tert.butylphenol find sizes energy homolitic dissociation О - Н of communications - D (OH). Values energy formation and energy of homolytic cleavage D (OH) communications in molecules of phenols depend on calculation approach ( РМ 6 or РМ 3) and parametres of a method of Hartrii-Focka. Dependences D (OH) from k 7 reactions 4-substituted 2,6-di- tert.butylphenol with peroxy cumene radical are investigated. Results of calculations D (OH) hindered of phenols in approach РМ 6 with RHF method are closest to experimental data/
