Abstract

ESR andIR spectroscopy and quantum chemical calculations are used to obtain the mechanistic data on the reaction Open image in new window . The IR bands are assigned by simulating the vibrational spectra of model low-molecular compounds. Quantum chemical calculations provided the data on the shapes of potential energy surface for the systems under study and transition states. These data are used to interpret the experimental data. The title reaction occurs much more readily in the case of organosilicon peroxy radicals than in the case of their hydrocarbon analogs. Surface silanone groups of silica react with ethylene molecules to form the siloxacyclobutane group.
