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. 640280-28-0, name is 1-Bromo-2-iodo-4-(trifluoromethyl)benzene, A new synthetic method of this compound is introduced below., name: 1-Bromo-2-iodo-4-(trifluoromethyl)benzene
To the N2 purged solution of TEA (10 ml) and DMF (10 ml) was added but-3-yn-1-ol (0.75 g, 10.69 mmol), 1-bromo-2-iodo-4-(trifluoromethyl)benzene (2.5g, 7.12 mmol), copper(I) iodide (0.27g, 1.425 mmol), bis(triphenylphosphine)palladium(II) chloride (0. 50g, 0.712 mmol) at room temperature and stirred further for 15 mm. After completionof reaction as indicated by TLC, reaction mass was poured in to water and extracted with ethyl acetate. The combined organic layer was dried over Na2SO4, conc under reduced pressure and purified by column chromatography to obtain title compound (1 .4g, 67%). LCMS (ESI): m/z 292.96(M+H)t
The synthetic route of 640280-28-0 has been constantly updated, and we look forward to future research findings.
