  The present invention is to provide a method of producing a carbonyl compound at a higher yield. The method of producing a carbonyl compound according to the present invention produces a carbonyl compound represented by general formula (I) by subjecting a compound represented by general formula (II) to dealkoxycarbonylation in the presence of a hydrogen halide salt of tertiary amine. In the formula, R represents an alkyl group having from 1 to 4 carbons.

  本发明提供了一种以更高产率生产酮基化合物的方法。根据本发明的生产酮基化合物的方法通过在三级胺的氢卤化盐存在下，使通式（II）表示的化合物经脱烷氧羰化反应产生通式（I）表示的酮基化合物。在该式中，R代表具有1至4个碳原子的烷基基团。

  In order to provide a novel method for producing a cyclopentanone compound, the present invention is a method for producing a cyclopentanone compound represented by the formula (I). The method includes the steps of: substituting the group represented by Y by a hydrogen atom by allowing a compound represented by the formula (III) or an intermediate compound obtained from the compound represented by the formula (III) to react with a catalyst or a halogenating agent; and substituting, by hydrogen atoms, (i) the group or the atom represented by Z 1 and (ii) the group or the atom represented by Z 2 , by reducing the compound represented by the formula (III) or the intermediate compound obtained from the compound represented by the formula (III).

  为了提供一种新颖的环戊酮化合物生产方法，本发明提供了一种生产由式(I)表示的环戊酮化合物的方法。该方法包括以下步骤：通过让式(III)表示的化合物或由式(III)表示的化合物得到的中间体与催化剂或卤化剂反应，将由Y表示的基团取代为氢原子；通过还原式(III)表示的化合物或由式(III)表示的化合物得到的中间体，将(i)由Z1表示的基团或原子和(ii)由Z2表示的基团或原子取代为氢原子。
