Reference of 619-58-9,Some common heterocyclic compound, 619-58-9, name is 4-Iodobenzoic acid, molecular formula is C7H5IO2, 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.
In a 100-mL resealable reaction tube, 4-iodobenzoic acid (10.0 g, 40.03 mmol) and furan-2- ylboronic acid (8.95 g, 80.06 mmol) were dissolved in degassed DMF (250 mL) and water (50 mL) at rt under nitrogen atmosphere. Pd(PPli3)4 (4.65 g, 3.99 mmol), K2CO3 (16.6 g, 120.09 mmol) were sequentially added to the above solution under nitrogen atmosphere. The resulting mixture was degassed by purging argon gas for 15 min, and reaction mixture was heated to 90C until completion of the reaction (TLC). The reaction mixture was cooled to rt, diluted with cold water and washed with ethyl acetate (3 x 30 mLl.The aqueous layer was separated and acidified to pH 3 with concentrated HC1, before extracting with EtOAc (100 mL x 2). The combined extract was washed with brine and concentrated under reduced pressure to get title compound (6.92 g, 92%) as light yellow solid. LCMS (m/: 187 (M-l)+.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 4-Iodobenzoic acid, its application will become more common.
