Reference of 54507-44-7,Some common heterocyclic compound, 54507-44-7, name is 2-Iodo-4-(trifluoromethyl)benzoic acid, molecular formula is C8H4F3IO2, 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.
Intermediate AI: S-trifluoromethyl-biphenyM-carboxylic acidA mixture of 2-iodo-4-trifluoromethyl-benzoic acid (CAS: 54507-44-7) (300 mg, 0.949 mmol) phenylboronic acid (239 mg, 1.898 mmol), sodium carbonate (302 mg, 2.847 mmol) and palladium (II) acetate (10.7 mg, 0.0475 mmol) in 4.5 ml water was stirred at room temperature for 48 hours. The mixture was filtered and the filtrate was acidified with HCl 37%. The mixture was stirred at room temperature for 30 minutes. The solid was filtered, washed with water and dried in vacuo to provide 225 mg (89 %) of the title compound as a brown solid. MS(m/e): 264.9 (M+H+).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 2-Iodo-4-(trifluoromethyl)benzoic acid, its application will become more common.
