Abstract
By means of hydrosilylation reactions between functional olefins and trieth oxysilane in the presence of Speier's catalyst and sol-gel transformations of the reaction products, a number of optically active and complexing alken es (quinine, quinidine, cinchonine, cinchonidine, alprenolol, N-allylrhodan ine and hemin) were immobilized on the surface of silica. The structures of the compounds formed and the nature of their bonding with the surface were studied by DRIFT and NMR spectroscopies. The concentrations of olefins anc hored to the surface layer of the silica matrix were estimated by UV spectr oscopy.
