摘要：

A method for preparing >Si(R-1)(R-2(.)) structures (R-1 = CH3, CD3, or CH2-CH3, R-2(.) = CH2-CH2. or CD2-CD2 .) grafted to a silica surface is developed. The reactions of intramolecular transfer of H (D) atoms between the R-1 and R-2(.) fragments were studied by ESR. The directions and kinetic parameters of these reactions were established.
