Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 628-77-3, name is 1,5-Diiodopentane, A new synthetic method of this compound is introduced below., Quality Control of 1,5-Diiodopentane
To a solution of 31 (400mg, 1 .5 mmol) in anhydrous DMF (4 mL), in a flask purged with argon, was added K2C03 (320 mg, 1.5 mmol) and 1 ,5-diiodopentane 32 (1.1 mL, 7.6 mmol). The reaction mixture was heated to 60C until complete (30 minutes). The solution was diluted with CH2CI2 (50 mL) and washed with H20 (50 mL) and brine (50 mL) before the organics were dried with MgS04, filtered and the volatiles remove in vacuo. The crude material was purified by silica gel column chromatography (Hexane/EtOAc ; 100% to 3:7) to afford pure product 33 as a light brown foamy gum (61 1 mg, 87% yield). Analytical Data: RT 1 .51 min; MS (ES+) m/z (relative intensity) 458.95 ([M + H]+ , 100 ).
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.
