<P>PROBLEM TO BE SOLVED: To provide a production method for β,β-difluoro-α,β-unsaturated carbonyl compound, which more easily and practically produces a β,β-difluoro-α,β-unsaturated carbonyl compound and is suited to be used as an industrial production method. <P>SOLUTION: In the production method for β,β-difluoro-α,β-unsaturated carbonyl compound, a silyl enol ether is obtained by silylating a β,β,β-trifluorocarbonyl compound, in the presence of a base and using a silylation reagent, and a β,β-difluoro-α,β-unsaturated carbonyl compound is obtained from the silyl enol ether in the presence of a Lewis acid. <P>COPYRIGHT: (C)2012,JPO&INPIT |
