The synthesis method of 3-bromo-2-chloro-6- (trifluoromethyl) pyridine has various paths.
First, the compound containing the pyridine ring is used as the starting material to introduce bromine and chlorine atoms through halogenation reaction. If the appropriate substituted pyridine is selected, under specific reaction conditions, a brominating agent such as liquid bromine or N-bromosuccinimide (NBS) can be used to introduce bromine atoms into specific positions of the pyridine ring in the presence of catalysts such as iron powder or iron tribromide. Then, a suitable chlorinating agent, such as thionyl chloride or phosphorus oxychloride, is selected, and the chlorine atom is also connected to the pyridine ring under the control of suitable reaction temperature and time, and the purpose of introducing bromine and chlorine atoms at the desired position can be achieved by fine regulation of the reaction conditions.
Second, start with the strategy of constructing a pyridine ring. For example, using a nitrile compound containing trifluoromethyl and a β-dicarbonyl compound containing bromine and chlorine as raw materials, under the action of a basic catalyst, the pyridine ring is formed by cyclization reaction. In this process, the type and amount of basic catalyst and the choice of reaction solvent have a great influence on the reaction process and product yield. Commonly used basic catalysts such as sodium alcohol, sodium hydride, etc., have different basic strengths and solubility, which make the reaction show different effects. Solvents such as alcohols, ethers or polar aprotic solvents need to be carefully selected due to their different effects on the solubility and reactivity of the reactants.
Furthermore, the coupling reaction catalyzed by transition metals. Pyridine derivatives containing trifluoromethyl groups can be selected, brominated reagents and chlorinated reagents can be used, and bromine and chlorinated reagents can be introduced into the pyridine ring through the coupling reaction of carbon-halogen bonds under the action of transition metal catalysts such as palladium and nickel. In this method, the structure of the catalyst ligand has a significant impact on the reaction selectivity and activity. The electronic and spatial effects of the complexes formed by different ligands and transition metals are different, resulting in very different catalytic activity and selectivity. Therefore, rational design and screening of ligands is the key to improving the reaction effect.
Or, use the method of step-by-step functional group transformation. First, a functional group that is easy to convert is introduced into the pyridine ring, and then it is gradually converted into bromine and chlorine atoms through a series of chemical reactions. This path requires strict control of the reaction conditions at each step. The stability and reaction selectivity of the intermediate in each step need to be carefully considered in order to achieve the goal of efficient synthesis of 3-bromo-2-chloro-6 - (trifluoromethyl) pyridine.
