Some common heterocyclic compound, 401-81-0, name is 1-Iodo-3-(trifluoromethyl)benzene, molecular formula is C7H4F3I, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. Safety of 1-Iodo-3-(trifluoromethyl)benzene
General procedure: A mixture of thiol (0.5 mmol), aryl halide (0.6mmol), CuI (5 mol%, 4 mg), DABCO (10 mol%, 5.6 mg) K2CO3(2 equiv, 138 mg) and DME (3 ml) were added to an oven-dried sealed tube equipped with a stirring bar under nitrogen. The sealed tube was stirred in a preheated oil bath at 120 oC for 12 h. After being cooled to room temperature, the mixture was diluted with ethyl acetate(30 ml) and washed with saturated aqueous NaCl solution (3 x 15 ml).The organic phase was dried with anhydrous Na2SO4,filtered, and the solvent was removed under vacuum. The crude residue was purified by column chromatography on silica gel using ethyl acetate/hexanes as the eluent to give the desired sulphides.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 401-81-0, its application will become more common.
