Reaktionsschritte

In an atmosphere of argon, 4.6 mg (5.4×10-3 mmol) of Ru(OAc)2 [(S)-(-)-OcH-binap] complex and 220.4 mg (1.08 mmol) of 2-(4-isobutylphenyl)-propenoic acid were dissolved in 5.4 ml of methanol, and the resulting solution was put into a 100 ml capacity autoclave and stirred at 25° C. for 24 hours under a hydrogen pressure of 100 atm. The reaction solution was concentrated and then subjected to a silica gel column chromatography (eluting solution, ether) to obtain 211 mg of (S)-2-(4-isobutylphenyl)propionic acid with a yield of 94%.
