Electric Literature of 612-55-5,Some common heterocyclic compound, 612-55-5, name is 2-Iodonaphthalene, molecular formula is C10H7I, 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.
General procedure: A mixture of CuI (Sigma-Aldrich, 0.025 mmol, 5 mol%), anhydrousK3PO4 (0.65 mmol), 2-mercaptobenzimidazole (0.5mmol), DMSO (0.2 mL), and aryl halide (0.75 mmol) were addedto a reaction vial and a screw cap was fitted to it. The reactionmixture was stirred under air in a closed system at 100 C for24 h. The heterogeneous mixture was subsequently cooled toroom temperature and diluted with dichloromethane. The combinedorganic extracts were dried with anhydrous Na2SO4, andthe solvent was removed under reduced pressure. The crudeproduct was loaded into the column using minimal amounts ofdichloromethane and was purified by silica gel column chromatographyto afford the S-arylated product. The identity andpurity of products was confirmed by 1H NMR and 13C NMRspectroscopic analysis
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 2-Iodonaphthalene, its application will become more common.
