Реферат:
The interaction of methane with Pt(II) complexes is studied by ab initio quantum-chemical calculations. From the structures of the (CH4)Pt(Cl)(2)(PH3)(2) complex, the conclusion is drawn that the three-center 14-electron Pt(Cl)(2)(PH3) intermediate (T-complex) can be formed in solvents with the participation of acids or through the thermal (photochemical) abstraction of a phosphine ligand from the 16-electron Pt(Cl)(2)(PH3)(2) complex. The calculated reaction path of methane oxidative addition to the T-complex predicts the existence of the stable (eta(2)-CH4)Pt(Cl)(2)(PH3) complex with the heat of formation -Delta H approximate to 50 kJ/mol and the activation energy E* approximate to 54 kJ/mol. The structures and the vibrational spectra of possible stable compounds based on the T-complex as well as the structure and the vibrational frequencies of the transition state of this reaction are calculated. A molecular mechanism is suggested for methane activation on Pt(II) complexes.
