In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 14862-52-3, name is 3,5-Dibromochlorobenzene belongs to chlorides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. category: chlorides-buliding-blocks
General procedure: A mixture of 1,3-dibromo-5-chlorobenzene (2 g, 7.41 mmol), 9Hcarbazole(2.60 g, 15.56 mmol), tris(dibenzylideneacetone)dipalladium(339 mg, 0.37 mmol), 2-dicyclohexylphosphino-2?,6?-dimethoxy-1,1?-biphenyl (457 mg, 1.11 mmol) and sodium tert-butoxide (2.85 g,29.64 mmol) in 100 ml of toluene were heated at 80 C for 4 h underargon. After cooling down to room temperature, the mixture was extractedwith dichloromethane. The combined organic extracts weredried over Na2SO4 and evaporated under reduced pressure. The crudeproduct was purified by column chromatography on silica gel usingpetroleum ether/dichloromethane (PE/DCM, 8/1, v/v) as the eluent toafford the target compound (2.46 g, 75%).
The synthetic route of 14862-52-3 has been constantly updated, and we look forward to future research findings.
