Abstract

The present invention addresses the problem of providing a method that produces a higher yield of a carbonyl compound. In this production method for a carbonyl compound ,dealkoxycarbonylation of a compound represented by formula (II) is performed in the presence of a hydrogen halide salt of a tertiary amine in order to produce a carbonyl compound that is represented by formula (I). (In formula (II), R represents an alkyl group having a carbon number of 1- 4.)
