    • 6] (0.5 μmol), N,N-dimethylacetamide (5 mL), and 4-methoxybenzyl alcohol (50 mmol). A Teflon-coated magnetic stir bar was added, and the atmosphere of the reaction vessel was replaced by Ar. The reaction was initiated by irradiation of visible light (λ > 400 nm) with a 300 W Xe lamp equipped with a 400 nm cut off filter. Hydrogen evolution was confirmed and monitored by GC (TCD) analysis. Products in the liquid phase were confirmed by comparison of their GC (FID) retention times and GC-MS spectra with those of authentic data. Every 10 h, the reaction system was replaced by Ar to remove the evolved hydrogen. After the reaction, the catalyst was retrieved by precipitation method by addition of excess diethyl ether to the reaction solution. The retrieved I was washed with n-hexane and then air-dried prior to being used for the reuse experiment. The IR and CSI-MS spectra of the retrieved catalyst showed that the structure of I was preserved after the hydrogen evolution (Figures S3 and S4).
