Application of 455-13-0, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 455-13-0 name is 4-Iodobenzotrifluoride, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
General procedure: A mixture of propargyl alcohol (1.0g, 18mmol), 1-Iodo-3-trifluoromethoxy-benzene (5.14g, 18mmol), copper iodide (0.342g, 1.8mmol), dichlorobis (triphenylphosphine) palladium (II) (0.632g, 0.9mmol), diethylamine (30ml) was degassed for 10min. and stirred for 20hat 25-25C. Excess of diethyl amine was distilled off under vacuum. The residue was diluted with water (50ml) and extracted with ethyl acetate (3×50ml). The organic layer was washed with brine solution and dried over Na2SO4. The solvent was evaporated and the crude product was purified by column chromatography (10% Ethyl acetate in hexane) to obtain pure 3-(3-Trifluoromethoxy-phenyl)-prop-2-yn-1-ol (3.8g, 100%).
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 4-Iodobenzotrifluoride, and friends who are interested can also refer to it.
