Adding a certain compound to certain chemical reactions, such as: 14862-52-3, name is 3,5-Dibromochlorobenzene, belongs to chlorides-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 14862-52-3, Application In Synthesis of 3,5-Dibromochlorobenzene
In a 250ml round bottom flask, carbazole borate (0.02mol), 2-chloro-4,6-dibromobenzene (0.012mol) and tetrakis(triphenylphosphine) palladium (0.0006mol) added into 15ml of tetrahydrofuran THF, added 10ml 2M K2CO3 solution and stir at a certain speed, the obtained mixed solution reactant was heated and reflux at a reaction temperature of 80 C for 18h; after the reaction is completed, cool to room temperature and add 100ml of water, the resulting mixture was filtered and washed three times in 25 ml of dichloroethane, finally it was dried over anhydrous magnesium sulfate. The resulting residue was further separated and purified on a silica gel column, and then obtained intermediate product M14
