合物が通常用いられる。(2) Solvent The present invention is characterized by using a mixture of a hydrocarbon and an oxygen-containing organic compound as a reaction solvent. Any hydrocarbon that can exist as a liquid under the reaction conditions can be used, such as pentane, hexane,
Aliphatic hydrocarbons such as cyclohexane, aromatic hydrocarbons such as benzene, toluene, xylene, and mixtures thereof are commonly used.
含酸素有機化合物としては、例えば、酢酸、プロピオン
酸、安息香酸等の有機カルボン酸類、アセトン、メチル
エチルケトン等のケトン類、ジオキサン、テトラハイド
ロフラン、ジエチルエーテル等のエーテル類及びそれら
の混合物が好ましく用いられる。As the oxygen-containing organic compound, for example, organic carboxylic acids such as acetic acid, propionic acid, and benzoic acid, ketones such as acetone and methyl ethyl ketone, ethers such as dioxane, tetrahydrofuran, and diethyl ether, and mixtures thereof are preferably used. .

サンと酢酸との混合物での例を挙げれば、酢酸/ヘキサ
ン容量比で2/98〜30/70程度が好ましい結果を
与える。The optimal mixing ratio of hydrocarbon and oxygen-containing organic compound varies greatly depending on the types of both compounds used, but for example, in the case of a mixture of hexane and acetic acid, the acetic acid/hexane volume ratio is 2/98 to 2/98. A ratio of about 30/70 gives preferable results.
また、上記混合溶媒中における、原料アルコールの濃度
としては、通常1〜50重量%程度が好ましい。Further, the concentration of the raw material alcohol in the mixed solvent is usually preferably about 1 to 50% by weight.
(3)触媒
本発明は、触媒として遷移金属化合物及び必要に応じて
助触媒の存在下で実施される。(3) Catalyst The present invention is carried out in the presence of a transition metal compound as a catalyst and, if necessary, a co-catalyst.

ム化合物としてヨウ化ロジウムを用いる場合は、助触媒
としてヨウ素化合物を必ずしも追加する必要はない。Examples of the metal in the transition metal compound include rhodium, palladium, cobalt, nickel, etc., and examples of the promoter include halogen group atoms, trivalent phosphorus compounds, and the like. In particular, in the present invention, a combination of a rhodium compound as the transition metal compound and iodine as the co-catalyst gives preferable results. Specifically, as the rhodium compound, rhodium halide, rhodium carbonyl, rhodium acetate, etc. are generally used, and as the iodine promoter, iodine compounds such as Iz, former, alkyl iodide, etc. are generally used. Further, when rhodium iodide is used as the rhodium compound, it is not necessarily necessary to add an iodine compound as a promoter.

After cooling, the contents were taken out. The solvent was distilled off under reduced pressure.The residue was dissolved in Heniso 50@7 and diluted with 2N
-NaO)1 aqueous solution (100 m7) was added to extract the acid component into the aqueous layer. Hydrochloric acid was added to the extract, and the liberated acid was extracted into ether. The crude crystals obtained by distilling off the ether were recrystallized in n-hexane to give 6.9 g (33.5 mmol) of white crystals of α-(4-isobutylphenyl)propionic acid.
) was obtained (yield 60.8%).
