Synthetic Route of 63262-06-6,Some common heterocyclic compound, 63262-06-6, name is 1,4-Dibromo-2,5-diiodobenzene, molecular formula is C6H2Br2I2, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
Under an argon atmosphere, dibromodiiodobenzene (2.5 g, 5.1 mmol), Intermediate 3 (4.97 g, 15.4 mmol), and Pd(PPh3)4 (237 mg, 0.205 mmol) were dissolved in toluene (250 mE) and dimethylsulfoxide (DMSO, 50 mE), 2 MNa2CO3 aqueous solution (13 mE) was added thereto, and the mixture was stirred with heating at 90 C. for 24 hours. Afier completion of the reaction, toluene was removed under reduced pressure, and the precipitated solid was filtered off. This solid was washed with methanol and ethyl acetate,whereby obtaining a white solid (2.5 g, yield: 75%). The obtained solid was Intermediate 4, which is an intended product, and by mass spectrum analysis, it was confirmed that it had an mle value of 626 with respect to a molecular weight of 626.
The synthetic route of 63262-06-6 has been constantly updated, and we look forward to future research findings.
