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, COA of Formula: C6H3Br2I
Into a 100ml two-necked flask feed 2, 4-dibromo-1-iodobenzene (3.6g), trimethylsilylacetylene (1. 1g), CuI (O.11g), Pd(PPh3)2C12 (0.21g) molar ratio is based on 1:1.1 :0.06:0.03, solvent selection as 50ml anhydrous tetrahydrofuran, anhydrous anaerobic conditions are controlled at 0 C, stir for 30 minutes, distillation under reduced pressure and then obtained 3.16g of ((2,4-dibromophenyl) ethynyl) trimethylsilane, yield is 95%.
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 2,4-Dibromo-1-iodobenzene, and friends who are interested can also refer to it.
