| titleOfInvention | Method for producing bis (4-oxocyclohexyl) s |
| abstract | (57) [PROBLEMS] To obtain a bis (4-oxocyclohexyl) compound from a bis (4-hydroxycyclohexyl) compound as a starting material under a mild reaction condition which is industrially easy to carry out. Provided is a method for producing bis (4-oxocyclohexyl) s that can be obtained with high selectivity. SOLUTION: General formula (I) [Wherein, X is a single bond, general formula (II)] (Wherein, R 1 and R 2 each independently represent a hydrogen atom, Represents an alkyl group having 6 to 6, a cycloalkyl group having 5 or 6 carbon atoms, or a phenyl group. ), A hydrocarbon group represented by -O- or -SO 2 - shows a. In a liquid phase comprising an unsaturated ketone solvent having a carbon-carbon double bond conjugated to a C ＝ O double bond, in the presence of a copper-based oxide catalyst. After dehydrogenation, general formula (III) (Wherein X, R 1 and R 2 are the same as described above), to produce bis (4-oxocyclohexyl) s. |
