摘要： PROBLEM TO BE SOLVED: To provide a method of efficiently producing a various species of 4-polyfluoroacylphenylalkyl ketones at a low cost using a simple process.
SOLUTION: A 4-polyfluoroacylphenylalkyl ketone represented by formula (4) is produced by allowing a ketone compound comprising a phenyl group or a substituted phenyl group to react with a silicon compound and an ester compound comprising a perfluoroalkyl group in an organic solvent in the presence of a reducing agent to convert the same into an acetal compound and subsequently treating the acetal compound with a desilylation agent (in the formula, R
1 represents a 1-8C alkyl group or a 3-8C cycloalkyl group, Rf represents a 1-4C poly or perfluoroalkyl group, R represents a hydrogen atom or a substituent, and n represents an integer of 1 to 4).
