Procedure

Platinum black (19.5 mg, 0.100 mmol) and benzyl alcohol (1.0 ml, 10 mmol) were mixed and stirred at 90° C. for 10 minutes. A 30% aqueous hydrogen peroxide solution (1.3 ml, 12 mmol) was gradually added dropwise to the mixed solution, followed by stirring at 90° C. for 15 hours, and then the reaction solution was cooled to room temperature. As a result of measurement by GLC, it was found that benzaldehyde was obtained in yield of 85%. Benzoic acid was obtained in yield of 0.7%.
