Procedure

RuClCp* (cod) (3.8 mg, 0.01 mmol), KOH (0.04 mmol), 2,2′-bipyridyl (3.1 mg, 0.02 mmol) and benzalacetone (730.95 mg, 5.0 mmol) were dissolved into 10 ml of 2-propanol, and deaerated by argon substitution, after which the total amount of the resulting mixture was transferred into a 100-milliliter metallic autoclave. Hydrogen was then charged to a predetermined pressure (4 atm), and the reaction was started at room temperature (28° C.) After the reaction solution was stirred for 18 hours, the reaction pressure was brought back to atmospheric pressure, and the reaction product, 4-phenyl-2-butanone (yield 87.7%), was identified and quantitatively determined by TLC monitor (silica gel: n-hexane/ethyl acetate=4/1) and gas chromatography of the reaction solution. At this time, 12.3% of the raw material, benzalacetone, was recovered.
