Adding a certain compound to certain chemical reactions, such as: 199786-58-8, name is (5-Bromo-2-iodophenyl)methanol, belongs to iodides-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 199786-58-8, Product Details of 199786-58-8
To a stirred mixture of alcohol 2-iodo-5-bromobenzyl alcohol (9.14 g, 29.2 mmol) in of CH3Cl (150 mL) under argon was added 1M PBr3 in CH2Cl2 (35.0 mL, 35.0 mmol). The reaction mixture was stirred at room temperature for 20 minutes and then poured into a mixture of ice and saturated NaHCO3 solution (300 mL). The pH was adjusted to basic by addition of solid NaHCO3. This aqueous layer was extracted with EtOAc (1×600 mL, 2×400 mL). The combined EtOAc extracts were washed with brine (1×100 mL). The organic layer was dried (MgSO4), filtered and concentrated in vacuo to give 2-iodo-5-bromobenzyl bromide (5.69 g, 52%). 1H NMR (CDCl3): delta=7.68 (d, 1H, J=8.80 Hz), 7.59 (s, 1H), 7.18 (d, 1H, J=8.80 Hz), 4.51 (s, 2H). HPLC: Rt=3.87 min.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, (5-Bromo-2-iodophenyl)methanol, other downstream synthetic routes, hurry up and to see.
