Electric Literature of 629-09-4, A common heterocyclic compound, 629-09-4, name is 1,6-Diiodohexane, molecular formula is C6H12I2, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
Step-1 : Synthesis of 2-(6-iodohexyl)isoindoline-l,3-dione (3377) [1175] To a suspension of potassium phthalamide (700 mg, 3.7 mmol) in DMF (30 mL) was added 1 ,6-diiodohexane (3.83 g, 11.33 mmol) and the reaction mass was heated atw 80 C for 1 h. (The reaction mass became clear on heating). The reaction mixture was cooled to RT, diluted with diethyl ether (100 mL) and water (100 mL), the organic layers were separated, and the aqueous layer was again extracted with diethyl ether (2×100 mL). The combined organic layer was washed with water (200 mL) and saturated brine solution (200 mL) The organic layer was dried over anhydrous sodium sulfate and concentrated under reduced pressure to obtain the product, which was purified by column (3378) chromatography (silica gel: 100-200 mesh; Eluent: 10 % ethyl acetate in hexane) to obtain pure product as white solid (2.1 g).
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
