Related Products of 618-91-7, 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. 618-91-7, name is Methyl 3-iodobenzoate belongs to iodides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
Cu [(I)] iodide (10 mg, 0.05 mmol), potassium carbonate (276 mg, 2.0 mmol) and Methyl 3-iodobenzoate (276 mg, 1.0 mmol) were charged into a screw-capped test tube with Teflon-lining. The tube was evacuated and backfilled with argon (3 cycles). Anhydrous DME (1.0 mL) and 3-methoxythiophenol (124 muL, 1.0 mmol) were added by syringes at room temperature. The tube was heated to [80 C] and stirred for 22 hours. The reaction mixture was then allowed to reach room temperature. Ethyl acetate (approx. 5 mL) and dodecane (227 [AL,] GC standard) were added. The aliquot was analyzed GC. The reaction mixture was then filtered and concentrated. The crude product was purified by column chromatography on silica gel using hexane/ethyl acetate = 20/1 to afford colorless liquid as the titled product (220 mg, 81% yield). Rf= 0.5 (hexane/ethyl acetate = [10/1).
