Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 20691-72-9, name is 4-Iodo-2-nitroaniline, A new synthetic method of this compound is introduced below., Product Details of 20691-72-9
To a stirred solution of SnC¾ (78.0 g, 346 mmol) in concentrated HC1 (150 mL) was added 2 (25.4 g, 92.0 mmol) in three portions over 30 min at rt. The reaction mixture was heated at 70 C for 1 h and then stirred at 0 C overnight. The mixture was treated with ¾0 (150 mL) and stirred for 2 h. The precipitate was collected by filtration and dried under vacuum to afford 3 (17 g, 81% yield) as a grey solid. LC-MS (ESI) m/z 235.0 (M + H)+.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
