A mixture of K2CO3 (1 mmol) and the catalyst (52 mg, ?3 mol% of Pd2+) in toluene (5 ml) was prepared in a two necked flask. The flask was evacuated and refilled with pure oxygen. To this solution, the alcohol (1 mmol, in 1 ml toluene) was injected and the resulting mixture was stirred at 80 C under an oxygen atmosphere. After completion of reaction, the reaction mixture was filtered off and the catalyst rinsed twice with CH2Cl2 (5 ml). The excess of solvent was removed under reduced pressure to give the corresponding carbonyl compounds.

General procedure: A solution of pure TsNHNH2 (15 mmol) in methanol (30 mL) was stirred and heated to 60 C until the TsNHNH2 dissolved. The mixture was cooled to room temperature. Then a solution of ferrocenylketone (10 mmol) in methanol was dropped into the mixture slowly. After approximately 0.5-2 h, the crude products could be obtained as solid precipitate. The precipitate was washed with petroleum ether then removed in vacuo to give the pure products. In general, the yields were 68-86 %. Because of the relatively low activity of some ketones, their reactions at room temperature may be incomplete. They should be reacted in refluxing methanol. The reaction could be monitored by TLC.
