実験手順
To a solution of 1,1-dimethyl-2,5-dihydro-1H-silole (3.0 g, 26.7 mmol) in acetonitrile (50 mL) was added phenyltrimethylammonium tribromide (1.0 g, 2.67 mmol) and chloramine-T (6.69 g, 29.4 mmol). After stirring at rt overnight the reaction mixture was filtered though a pad of Celite and concentrated under vacuum. Purification by silica gel chromatography (20% EtOAc/hexanes) afforded the desired product.
