Continuously updated synthesis method about 116632-39-4

The chemical industry reduces the impact on the environment during synthesis 5-Bromo-2-iodotoluene. I believe this compound will play a more active role in future production and life.

116632-39-4, The chemical industry reduces the impact on the environment during synthesis 116632-39-4, name is 5-Bromo-2-iodotoluene, I believe this compound will play a more active role in future production and life.

A Schienk tube was charged with compound 480 (402 mg, 1.31 MMOL) in 1,4-dioxane (3.0 mL), 5-BROMO-1-IODO-TOLUENE (358 mg, 1.19 MMOL), sodium tert-butoxide (160 mg, 1.67 MMOL), PD2 (dba) 3 (27 mg, 0.03 MMOL), and rac-BINAP (28 mg, 0.045 MMOL). The tube was capped with a rubber septum, flushed with argon for 5 min, and then stirred at 100 C for 72 h. The reaction mixture was allowed to cool to RT, and then poured into a mixture of water and EtOAc. The aqueous phase was extracted twice with more EtOAc. The combined organic phases were washed with brine, dried (MGSO4), filtered and concentrated in vacuo. The crude product was purified by chromatography eluting with petroleum ether/EtOAc 4: 1 to afford the title compound as yellow oil. 13C NMR (CI3) 8 195.4, 160.6, 147.7, 141.9, 137.7, 134.3, 134.0, 133.9, 133.4, 132.6, 131.6, 130.3, 130.0, 124.5, 117.6, 117.6, 116.1, 112.9, 111.0, 81.7, 67.0, 21.3, 17.8
