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. 63262-06-6, name is 1,4-Dibromo-2,5-diiodobenzene, A new synthetic method of this compound is introduced below., Recommanded Product: 63262-06-6
Under a nitrogen atmosphere, to a 50mL three-necked flask 1,4-dibromo-2,5-di-iodobenzene 219 mg (0.45 mmol) and diethyl ether (5 ml) was added and cooled to -78 C..Thereafter, it was added dropwise n- butyllithium 0.54ml at the same temperature (1.66 M hexane solution, 0.90 mmol), and stirred for 1 hour.At Thereafter the same temperature, it was added dropwise synthesized bis previous step was dissolved in diethyl ether (1ml) (2-n- hexyl-4-thienyl) disulfide 359 mg (0.90 mmol), and stirred at room temperature for 12 hours.The reaction by the addition of water was stopped, after extraction with diethyl ether, and the organic layer was dried over anhydrous sodium sulfate.And concentrated under reduced pressure, the resulting residue was purified by silica gel column chromatography (hexane), 1,4-bis [(2-n-hexyl-4-thienyl) sulfanyl] of 2,5-dibromobenzene yellow solid 228mg was obtained (80% yield).
The synthetic route of 63262-06-6 has been constantly updated, and we look forward to future research findings.
