YieldReaction ConditionsOperation in experiment
94% General procedure: Bromo-phen (4-bromo-phen, 3-bromo-phen, 2-bromo-phen, 3,8-dibromo-phen, 2,9-dibromo-phen, 3.86mmol) and KBr (4.59g, 38.6mmol) were added into a mixture of HNO3 (1.4g/mL, 10mL) and H2SO4 (1.84g/mL, 20mL) at 0C, and the mixture was heated under stirring (80-110C for 3h). After cooled to room temperature, the solution was poured into a mixture of ice (100g) and water (200mL) and neutralized carefully with a 1mol/L sodium hydroxide solution until the pH=7. The suspension was filtrated, washed with water and dried in vacuo. Purification by silica gel column chromatography using CHCl3 as the eluent gave corresponding bromo-phds (1a-1e) with yields of 11-94%, as shown in Scheme 1. It is worth pointing out that another two dibromo-phds 2a and 2c could be also isolated in the temperature of 90-110C with 10-55% yields during the syntheses of 1a and 1c. In addition, two hydroxylation products, i.e. 3 and 5, were separated successfully in the after-treatment process of 4-bromo-phen oxidative reaction.
