Adding a certain compound to certain chemical reactions, such as: 103962-05-6, name is 1-Iodo-4-(trifluoromethoxy)benzene, 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 103962-05-6, Computed Properties of C7H4F3IO
To a 250 mL reaction flask was added 3-bromo-1H-1,2,4-triazole (5 g, 33.8 mmol), CuI (0.644 g, 3.38 mmol) and Cs2CO3 (11.01 g, 33.8 mmol). The flask was evacuated/backfilled with nitrogen gas, and then DMSO (33.8 ml) and 1-iodo-4-(trifluoromethoxy)benzene (4.87 g, 16.90 mmol) were added. The reaction mixture was heated to 100° C. for 20 hours (h). The reaction wascooled to room temperature (RT), diluted with EtOAc and filtered through a plug of Celite®. The Celite® was further washed with EtOAc. Water was added to the combined organics, and the layers were separated. The aqueous phase was neutralized to pH 7, and further extracted with EtOAc. The combined organics were concentrated in vacuo. Purification via flash column chromatography using EtOAc/hexanes as eluent provided the title compound as an off-white solid (3.78 g, 73percent): mp 69-70° C.; 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]+)
