Abstract
The mechanism of cyclopropane interaction with (=Si-O-)(3)Si-O-. param agnetic centers stabilized on the SiO2 surface (RSi) is studied by EPR at 300 and 150 K. The primary products of the free-radical reaction a re identified. It is shown that the major product is the cyclopropyl r adical. No products arising from cycle-opening cyclopropane addition t o the radical are found. This implies that the relative yield of this reaction is below 0.5%.
