Adding a certain compound to certain chemical reactions, such as: 19393-94-3, name is 2,4-Dibromo-1-iodobenzene, 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 19393-94-3, Computed Properties of C6H3Br2I
General procedure: An oven-dried Schlenk tube was charged with a magneticstir bar, binucleophile 2-mercaptobenzimidazole 2 (1.0 mmol, 1.0 equiv), CuI(0.1 mmol, 10 mol %), phen (0.2 mmol, 20 mol %), and K2CO3 (2.0 mmol, 2equiv). The tube was capped and then evacuated and backfilled with nitrogen(3 times). Under a positive pressure of nitrogen, a solution of o-dihaloarene 1(1.05 mmol, 1.05 equiv) in DMF (3 mL) was added via syringe. The tube wassealed and allowed to stir at 120 C (monitored by TLC). After being cooled toroom temperature, EtOAc (40 mL) was added and the mixture was washedwith brine (20 mL 3). The organic phase was dried over Na2SO4 andconcentrated. The residue was purified by column chromatography on silicagel using petrol/EtOAc (10:1?3:1, v:v) as eluent to give product 3.
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, 2,4-Dibromo-1-iodobenzene, other downstream synthetic routes, hurry up and to see.
