Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 20555-91-3.

Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 20555-91-3, name is 1,2-Dichloro-4-iodobenzene, This compound has unique chemical properties. The synthetic route is as follows., Formula: C6H3Cl2I

To a solution of l,2-dichloro-4-iodobenzene (Intermediate la) (5.6g, 20.75mmol), tert-butyl 4-(but-3-yn-2-ylcarbamoyl) piperazine-l-carboxylate (Intermediate 8) (7g, 24.9lmmol) and triethyl amine(8.66mL, 62.25mmol) in DMF(lOOmL) was purged with argon gas for 20 min. Then Copper Iodide (0.79g, 4.l5mmol) and Tetrakis(triphenylphosphine) palladium(O) (2.39g, 2.07 mmol) were added at RT and the reaction mixture was again purged for 10 min. The reaction mixture was stirred for 2h at 80C. After completion of reaction, it was poured into ice water and extracted with EtOAc. The EtOAc layer was dried; concentrated and purified by combiFlash silica gel column (hexanes/EtOAc=40/60) to obtain the title compound (7.0g, 79.8%). LCMS: m/z =426.1 [M]+.

Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 20555-91-3.
