Application of 67515-59-7, A common heterocyclic compound, 67515-59-7, name is 4-Fluoro-3-(trifluoromethyl)benzonitrile, molecular formula is C8H3F4N, its 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.
General procedure: A mixture of 9H,9’H-3,3′-bicarbazole (500 mg, 1.50 mmol), 4-fluoro-2-methylbenzonitrile (450 mg, 3.33 mmol) and K2CO3(0.99 g, 7.2 mmol) in dimethyl sulfoxide (DMSO) (6 mL) was stirredat 140 C for 12 h under nitrogen atmosphere. After cooling to roomtemperature, the mixture was poured into water, filtered and thenpurified by column chromatography over silica gel with CH2Cl2/petroleum ether (1: 1) as eluent to afford a white solid (760 mg,89%).
The synthetic route of 67515-59-7 has been constantly updated, and we look forward to future research findings.
