Abstract: | Chemical assembling of the silica surface modified by dimethylchlorosilane was performed by the catalytic hydrosilylation
of 1,3-divinyl-1,1,3,3-tetramethyldisiloxane, α-methyl styrene, acetophenone, allyl butyl and allyl glycidyl ethers with dimethylchlorosilane.
The effect of the nature of complexes of platinum, palladium, rhodium and ruthenium on the parameters of hydrosilylation was
studied. It was shown that the maximum rate of hydrosilylation was observed in the reaction with allyl glycidyl ether, and
minimum, with α-methylstyrene; the most effective catalyst of hydrosilylation was Rh(CO)2(acac)]. |
