Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 56961-77-4, name is 1-Bromo-2,3-dichlorobenzene, A new synthetic method of this compound is introduced below., Safety of 1-Bromo-2,3-dichlorobenzene
31.8 g (100.0 mmol) of Compound 11-A, 22.6 g (100.0 mmol) of Compound 1-B, 2.7 g (3.0 mmol) of Pd2(dba)3, 1.3 g (6.0 mmol) of PtBu3 (50% solution in toluene), 28.8 g (300.0 mmol) of NaOtBu were mixed with 1,500 mL of toluene under a nitrogen (N2) atmosphere, followed by stirring under reflux to allow a reaction to occur for 12 hours. At room temperature, an organic layer was separated therefrom using water and ethyl acetate, and the solvent was dried. Then, through silica gel column chromatography, 20.9 g of Compound 11-C was obtained at a yield of 45%. [0313] MS (MALDI-TOF) m/z: 463 [M]+
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
