Abstract
LiCl efficiently catalyzes cyanosilylation of various hetero-substituted ketones. α,α-Dialkoxy ketones are completely converted to silylated cyanohydrins with a substrate-to-catalyst molar ratio of 100,000 at room temperature. Acetophenones substituted by an electron-attracting group at the ortho or para position show higher reactivity than substrates with an electron-donating function.
Keywords: silylated cyanohydrins, lithium chloride, hetero-substituted ketones, cyanotrimethylsilane, cyanosilylation, Catalytic reaction
