4-Bromo-2-nitrophenol synthesis

13synthesis methods
The synthesis method of 4-bromo-2-nitrophenol comprises the following steps: preparing nitric acid with a concentration of 7-8 M; dissolving p-bromophenol in dichloroethane to obtain a substrate with a concentration of 1.8-2.2 M; injecting the nitric acid and the substrate into a continuous flow reactor through two pumps respectively, mixing, controlling the temperature at 55-75°C, the reaction pressure at 0.35-0.45 MPa, and reacting for 20-30 min.

Yield:7693-52-9 100%

Reaction Conditions:

with sulfuric acid;C20H22Br2N2O5V;dihydrogen peroxide in methanol;lithium hydroxide monohydrate at 20; for 0.583333 h;Catalytic behavior;Reagent/catalyst;Solvent;

Steps:

2.5. General procedure of the oxidative bromination reaction

General procedure: In a 10-mL round-bottom flask equipped with a magnetic stirring bar, 1 mM of the 2-nitrophenol was reacted with different amounts of the oxidant, acid, bromide source, and the vanadyl Schiff base complex in 4 mL of solvent. The content was stirred at room temperature.The progress of the reaction was monitored by GLC.
