Adding a certain compound to certain chemical reactions, such as: 5100-98-1, name is 3-Chloro-2-iodotoluene, 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 5100-98-1, Quality Control of 3-Chloro-2-iodotoluene
General procedure: A mixture of 17 (200 mg, 0.369 mmol), 2-bromo-1-methoxy-3-methylbenzene(148 mg, 0.737 mmol), Pd(OAc)2 (8.3 mg, 0.037 mmol), 2-dicyclohexylphosphino-2?,6?-di-isopropoxy-1,1?-biphenyl (34.4 mg,0.074 mmol), and Cs2CO3 (360 mg, 1.11 mmol) in toluene (7.5 ml) and water (1.5 ml) was stirred at 80 ¡ãC for 25 h. Then, water was added tothe reaction mixture, and the product was extracted with AcOEt. Theorganic layer was successively washed with water and brine, dried overanhydrous Na2SO4 and concentrated in vacuo. The residue was purifiedby silica gel column chromatography (hexane/AcOEt=40/60 to 10/90) to give the title compound as a white solid (43 mg, 21percent).
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 3-Chloro-2-iodotoluene, and friends who are interested can also refer to it.
