Adding a certain compound to certain chemical reactions, such as: 33348-34-4, name is 4-Amino-3-iodobenzonitrile, 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 33348-34-4, Application In Synthesis of 4-Amino-3-iodobenzonitrile
2-(4,4-Dimethyl-[1,3,2]dioxaboronan-2-yl)-benzoic acid ethyl ester (19.84 g) , 2-iodo-4-cyanoaniline (18.47 g), tetrakis(triphenylphosphine) palladium (8.75 g) and potassium phosphate (35.36 g) were added to dioxane (360 ml), and the resulting mixture was heated under reflux overnight. The reaction solvent was cooled, and the produced solid was collected by filtration, washed with water and dried to thereby obtain 17.3 g (yield: quantitative) of the title compound as a yellow solid. 1H-NMR(DMSO-de) dppm: 7.47 (lH,d,J=8.5Hz), 7.6-8.0 (3H,m), 8.1-8.2 (IH,m), 8.3-8.4 (IH,m), 8.98 (IH,s), 12.05(lH,brs)
