METHOD FOR PRODUCING HALOCARBONYL COMPOUND

To provide a method for producing a halocarbonyl compound in good yield without requiring an expensive oxidizing agent or a metal salt which is feared to reside, while suppressing an amount of use of a halogen cation source.SOLUTION: There is provided a method for producing a halocarbonyl compound, including a reaction step of electrolytically reacting a cyclic compound represented by the following formula (1) in a solution containing a halide salt and an ammonium salt to obtain a halocarbonyl compound represented by the following formula (1'). The cyclic compound represented by the following formula (1) is a compound having a ring A having a hydroxy group and R1. In the formula (1) or (1'), R1 represents hydrogen or a monovalent organic group; R2 represents an optionally substituted divalent hydrocarbon group having 2 to 12 carbon atoms, and the carbon atoms constituting the hydrocarbon group may be substituted with nitrogen, oxygen, or sulfur; and Z represents a halogen group.SELECTED DRAWING: None 【課題】ハロゲンカチオン源の使用量を抑制しつつ、高価な酸化剤や残留が懸念される金属塩を必要とせずにハロカルボニル化合物を収率よく製造する方法を提供する。【解決手段】下記式（１）で表される環状化合物を、ハロゲン化塩及びアンモニウム塩を含む溶液中で電解反応させて下記式（１'）で表されるハロカルボニル化合物を得る反応工程を有する、ハロカルボニル化合物の製造方法。下記式（１）で表される環状化合物は、ヒドロキシ基及びＲ１を有する環Ａを有する化合物であり；式（１）または（１'）において、Ｒ１は、水素、又は１価の有機基を表し；Ｒ２は、置換基を有していてもよい炭素数２～１２の２価の炭化水素基を表し、かつ、該炭化水素基を構成する炭素が窒素、酸素、又は硫黄で置換されていてもよく；Ｚは、ハロゲン基を表す。TIFF2022140148000021.tif32170【選択図】なし
