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. 627-31-6, name is 1,3-Diiodopropane(stabilized with Copper chip), A new synthetic method of this compound is introduced below., COA of Formula: C3H6I2
Preparation of 1,3-bis(1-isoquinolyl)-propane 2a; A solution of 2-benzoyl-1-cyano-1,2-dihydroisoquinoline 1a (5.0 g; 19.2 mmol) and of 1,3-diiodopropane (1.1 mL; 9.6 mmol) in DMF (15 mL) was dropwise added to a stirred suspension of sodium hydride (0.46 g; 19.2 mmol) in DMF (30 mL) at -10 C. The content was stirred for 4 h and poured into ice-cold water (200 mL). The creamy solid was filtered off. After drying, the solid was hydrolyzed by treatment with 50% aqueous NaOH in EtOH at reflux. After removal of EtOH, the crude residue was dissolved in ArMe (50 mL) and water (50 mL). The organic layer was collected, washed with water (50 mL) and then extracted with 1N aqueous HCl (2×50 mL). The acidic layers were basified with concentrated NH4OH and finally extracted with CH2Cl2 (3×30 mL). The organic layers were dried over anhydrous MgSO4 and evaporated under reduced pressure to afford a white solid which recrystallized from petroleum ether 100-140 (2.5 g); yield, 40%; mp 96-97 C.1H-NMR (CDCl3) delta 2.49 (pentuplet, 2H, J=7.7 Hz), 3.50 (t, 4H, J=7.7 Hz), 7.51 (d, 2H, J=5.7 Hz), 7.56 (t, 2H, J=7.5 Hz), 7.65 (t, 2H, J=7.5 Hz), 7.80 (d, 2H, J=7.5 Hz), 8.18 (d, 2H, J=7.5 Hz), 8.44 (d, 2H, J=5.7 Hz)Anal.

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.
