l-Iodo-3-(trifluoromethoxy)benzene:; To 3-(trifluoromethoxy)beπzenamine (17.7 g, 100.00 mmol) was added a solution OfNaNO2 (7.4 g, 115.62 mmol) in H2O (80 ml). H2SO4 (25 g, 250.00 mmol) was added dropwise with stirring at -5 °C. The resulting solution was kept at -5 °C for 15 minutes. To this solution was added a solution of KI (20 g, 120,48 mmol) in H2O (60 ml) dropwise, The resulting solution was stirred overnight at room temperature and extracted with EtOAc (2 X 100 mL). The combined organic layers were washed with Na2SO3/H2O (2 X 50 mL), dried over Na2SO4 and concentrated in vacuo. The residue was purified by silica gel column chromatography to afford 4.0 g (14percent) of l-iodo-3- (trifluoromethoxy)benzene. |
