Verwenden

Trimethylsilylacetone reacts with Grignard or organolithium reagents to provide, after elimination, 2-substituted 2-propenes; in combination with fluoride ion, gives chemistry of the corresponding enolate ion; can direct electrophilic substitution to either side of the carbonyl group, participating in (but not limited to) reactions: Preparation of 2-substituted α-Alkenes, Reaction with Electrophiles, Reaction with Fluoride Ion, Reaction with Strong Bases, etc.

synthetische

The best procedure for the preparation of trimethylsilylacetone is the reaction of trimethylsilylmethylmagnesium chloride or bromide with acetic anhydride.5 Other useful preparative methods for α-trimethylsilyl ketones involve the reaction of trimethylsilylmethylmagnesium chloride with acid chlorides,6 or with aldehydes followed by oxidation of the resulting β-hydroxysilane to the ketone.2e When the trialkylsilyl group is very large, particularly the triisopropylsilyl group, a rearrangement from the silyl enol ether to the α-silyl ketone is possible.
