Conclusions 1. The reactions of pentafluorophenyltrimethylsilane with substituted acetophenones, initiated by cyanide anions, can be significantly retarded or rendered as unrealizable under the influence of electronic (e.g., 2, 3, 4, 5, 6-pentafluoroacetophenone) and/or steric (α,α,α-trifluoro-2,4,6-trimethylacetophenone) factors. 2. A high yield of the respective silyl ether of the enol is formed instead of the expected O-trimethylsilylated cyanohydrin in the catalytic reaction of the sterically hindered 2,4,6-trimethylacetophenone with trimethylcyanosilane.
