実験手順

A 200 ml capacity autoclave was charged with 30.4 g (200 mmol) of pulegone, 19.1 mg (0.02 mmol) of RuCl2(PPh3)3(propanediamine), 44.9 mg (0.4 mmol) of t-BuOK and 2-propanol (15 ml), and the mixture was stirred at 30° C. for 18 hours while forcing 3 Mpa of hydrogen. After completion of the reaction, hydrogen was purged and the reaction solution was concentrated and distilled under a reduced pressure to obtain 30.2 g of pulegol. The yield was 98%.
