Nanoporous silver (10 mg), acetone (1.5 mL), H2O(0.1 mL), and dimethylphenylsilane 1a (1 mmol) were added in a micro-reaction vial at room temperature. The mixture was stirred for 60 min until no bubbles emerged, and then the np-Ag was removed from the system. The reaction mixture was then concentrated by rotary evaporation and the residue was purified by column chromatography on silica gel using ethyl acetate/petroleum ether (60-90 °C) (1:1) as eluent to give 2a. The recovered catalyst was washed with acetone and water and was reused without further purification. |
