| Abstract: | A method for preparing >Si(R1(R2 .) structures (R1=CH3, CD3, or CH2−CH3, R2 .=CH2−CH2 . or CD2−CD2 .) grafted to a silica surface is developed. The reactions of intramolecular transfer of H (D) atoms between the R1 and R2 . fragments were studied by ESR. The directions and kinetic parameters of these reactions were established.
