Application of 2142-70-3, 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. 2142-70-3 name is 1-(2-Iodophenyl)ethanone, 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.
A sealed tube was charged with CuI (0.19g, 1.0mmol, 2.5 equiv.), AgF (0.13g, 1.0mmol, 2.5 equiv.), pyridine (0.27mL, 8.3 equiv.), various iodoarenes (0.4mmol, 1.0 equiv.), triethyl(1,1,2,2-tetrafluorobut-3-en-1-yl)silane (4 : 0.19g, 0.8mmol, 2.0 equiv.) and DMF (3.2mL, 0.25M) in glove box. The sealed tube was brought under an atmosphere of argon and capped. The resulting mixture was stirred at 60C for 16h, and then cooled room temperature. The resulting mixture was passed through short column. The eluent was concentrated in vacuo to give the crude materials, which were purified by silica gel column chromatography, leading to the desired coupling products
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 1-(2-Iodophenyl)ethanone, and friends who are interested can also refer to it.
