Synthetic Route of 14192-12-2,Some common heterocyclic compound, 14192-12-2, name is 2,5-Diiodobenzoic acid, molecular formula is C7H4I2O2, 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.
Step 1 : A RBF equipped with a reflux condenser was charged with 4-bromophenol (15.5 g, 89.4 mmol), 2,5-diiodobenzoic acid (25.700 g, 68.7 mmol), EtOAc (0.337 ml, 3.44 mmol), and toluene (100 mL). Cs2C03 (44.8 g, 137 mmol) was carefully added portion- wise. After stirring at RT for 1 min, the mixture was heated to 50 C for 40 min and then heated to 100 C for 20 hrs. The reaction mixture was allowed to cool to RT. The mixture was filtered through Celite and the solids were washed with EtOAc. The filtrate was diluted with water (200 mL), acidified with 2N HC1 (300 mL), and extracted with EtOAc (4 x 500 mL). The organic extract was washed with brine and dried over sodium sulfate. The organic fraction was concentrated under reduced pressure to afford crude 2- (4-bromophenoxy)-5-iodobenzoic acid (31.1 g) as a tan oil that solidified upon standing
The synthetic route of 14192-12-2 has been constantly updated, and we look forward to future research findings.
