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. 103962-05-6, name is 1-Iodo-4-(trifluoromethoxy)benzene, A new synthetic method of this compound is introduced below., Application In Synthesis of 1-Iodo-4-(trifluoromethoxy)benzene
A dry round bottom flask was charged with potassium phosphate (K3PO4, 7.74 g, 36.5 mmol), CuI (0.165 g, 0.868 mmol), and 3-bromo-1H-1,2,4-triazole (2.83 g, 19.10 mmol). The flask was evacuated/backfilled with N2 (3*). DMF (34.7 ml) was added, followed by trans-(1R,2R)-N,N’-bismethyl-1,2-cyclohexane diamine (0.274 ml, 1.736 mmol) and 1-iodo-4-(trifluoromethoxy)benzene (5 g, 17.36 mmol). The solution was heated to 110° C. After 48 h, the reaction mixture was cooled to RT, diluted with EtOAc and filtered through Celite®. The filtrate was washed with water (100 mL) containing 10 mL 1 M HCl. The organics were separated, and the aqueous phase was further extracted with EtOAc (3*). The organics were combined, dried, and concentrated in vacuo. Purification via flash column chromatography (EtOAc/hexanes) yielded the title compound as a tan solid (1.86 g, 34percent): 1H NMR (400 MHz, CDCl3) delta 8.44 (s, 1H), 7.70 (d, J=8.9 Hz, 2H), 7.38 (d, J=8.5 Hz, 2H); 19F NMR (376 MHz, CDCl3) delta -58.04; EIMS m/z 307 ([M]+).
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.
