Application of 41252-96-4, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 41252-96-4, name is 2-Chloro-1-iodo-4-nitrobenzene, This compound has unique chemical properties. The synthetic route is as follows.
Step A: Preparation of 2-chloro-4-nitro-biphenyl. A mixture of potassium carbonate (1.48 g, 10.7 mmol), phenylboronic acid (645 mg, 5.29 mmol), 3-chloro-4-iodonitro benzene (1.00 g, 3.53 mmol), and THF (31 ml) was degassed with nitrogen in a sealable tube for 10 min. The dichloromethane adduct of 1,1′-bis(diphenylphosphino)ferrocene]dichloro palladium (351 mg, 0.429 mmol) was added to the reaction mixture and the pressure tube was sealed. The reaction mixture was stirred at 100 C. for 42 h. The mixture was cooled to 23 C., diluted with DCM (40 ml), and filtered. The filtrate was concentrated. The residue was purified by FCC (3-50% EtOAc/hexanes) to yield the titled compound (796 mg, 97%). 1H NMR (600 MHz, DMSO-d6): 8.42-8.41 (m, 1H), 8.26 (dd, J=8.5, 2.2, Hz 1H), 7.72 (d, J=8.5 Hz, 1H), 7.55-7.48 (m, 5H).
The chemical industry reduces the impact on the environment during synthesis 2-Chloro-1-iodo-4-nitrobenzene. I believe this compound will play a more active role in future production and life.
