The synthetic route is as follows., Product Details of 138526-69-9
[10092] (1-1) In a nitrogen atmosphere, a solution prepared by dissolving 50 g of 3,4,5-trifluorobromobenzene in 50 mL of THF was added dropwise at a rate that caused gentle reflux to a mixed solution of 6.34 g of magnesium and 60 mL of THF. Afier dropwise addition, the mixture was stirred at 40 C. for 1 hout Then, a solution prepared by dissolving 34.64 g of DMF in 60 mL of THF was added dropwise under ice cooling at such a rate that the inside temperature did not exceed 20 C., followed by stirring at room temperature for 1 hout Then, 10% hydrochloric acid was added until the reaction system became acidic, and the mixture was stirred at room temperature for 1 hout Then, hexane was added to the mixture to separate an organic layer, and an aqueous layer was subjected to extraction with hexane. The hexane extract was combined with the organic layer and washed with a saturated aqueous sodium bicarbonate solution and saturated brine. The resultant mixture was dried by adding sodium sulfate, and then the solvent was distilled off under reduced pressure to yield 37.91 g of 3,4,5-trifluorobenzaldehyde.
According to the analysis of related databases, 138526-69-9, the application of this compound in the production field has become more and more popular.
