| titleOfInvention | Method for producing substituted alicyclic-1,3-dione |
| abstract | (57) Abstract: An alicyclic-1, 1 which is unstable under acid or basic conditions. Even in the case of a 3-dione compound, the precursor alicyclic- An object of the present invention is to provide a production method in which a 1,3-dione-4-carboxylate is subjected to a decarboxylation reaction under mild conditions to obtain a desired product in good yield without an industrial problem. SOLUTION: General formula (I) (Wherein, R 1 to R 5 each independently represent a hydrogen atom, a halogen atom, a C1 to C12 alkyl group which may have a substituent, or the like.) A salt of 2,3-dione-4-carboxylic acid is decarboxylated by adding a mineral acid in an aqueous solvent or a mixed solvent of water and a water-soluble organic solvent in a pH range of 7 to 10.5, to obtain a compound represented by the general formula ( II) (In the formula, R 1 to R 6 and n represent the same meaning as described above.) To produce a substituted alicyclic-1,3-dione represented by |
