Electric Literature of 3032-81-3, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 3032-81-3, name is 1,3-Dichloro-5-iodobenzene belongs to iodides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
To a solution of 1,3-dichloro-5-iodo-benzene in 1,4-dioxane (160 mL) was added Copper(I) iodide (0.661g), pyridine-2-carboxylic acid (0.812g), and cesium carbonate (32g) under Argon. Then dimethyl propanedioate (15g) was added at room temperature via dropping funnel.The mixture was heated to 90C for 5h. After completion of the reaction mixture was diluted with water and extracted with ethyl acetate (2x). the combinated organic layers were washed with brine, dried over sodium sulphate and concentrated. The crude was purified by silica gel column chromatography (3RF 200) using a gradient of ethyl acetate (0 to 10%) in cyclohexane to give the title compound (11.75 g, 77.1% Yield). LC-MS (method A): 277 (M+1)+, 275 (M-1)+retention time 1.02 min.
The synthetic route of 1,3-Dichloro-5-iodobenzene has been constantly updated, and we look forward to future research findings.
