Generally, it requires fewer steps, and cheap raw materials. 612-55-5, name is 2-Iodonaphthalene, A new synthetic method of this compound is introduced below., name: 2-Iodonaphthalene

General procedure: A mixture of aryl halide (1.0 mmol), alkene (1.1 mmol), triethylamine (2 mmol), DMF (5 mL), and the catalyst (30 mg, 0.28 mol% Pd ) was stirred at 80 C for an appropriate time under aerial condition. The progress of the reaction was monitored by TLC. After completion of the reaction, the mixture was cooled to room temperature, poured into H2O (10 mL), and the catalyst was separated by magnetic decantation. In the case of acrylic acid, aqueous solution of Na2CO3 (10 mL, 3% w/v) was added; after separation of the catalyst, and the product was extracted with ethyl acetate (3 × 10 mL).

As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 612-55-5, name is 2-Iodonaphthalene belongs to iodides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. HPLC of Formula: C10H7I

General procedure: For a typical reaction, a Vapourtec 2R+ Series was used as the platform with a Vapourtec Gas/Liquid Membrane Reactor to load the carbon monoxide. The HPLC pump were both set at 0.125 mL/min, temperature of the reactor at 110 C, pressure of CO at 15 bar with a back pressure regulator of 250 psi (17.24 bar). The system was left running for 2 h to reach steady state after which time the flow streams were switched to pass from the loops where the substrates and catalysts were loaded. The first loop (5 mL) was filled with a solution of palladium acetate (20 mg, 0.08 mmol), triphenylphosphine (48 mg, 0.168 mmol) in 6 mL of 1,4-dioxane while the second loop (5 mL) was filled with a solution made from the ortho-substituted iodoarene substrate (1.68 mmol), triethylamine (0.272 g, 0.374 mL, 2.69 mmol) and water (0.505 g, 28 mmol) in 5.8 mL of 1,4-dioxane. An Omnifit column filled with 1.71 cm3 (r = 0.33 cm, h = 5.00 cm) of cotton was positioned just before the back pressure regulator to trap any particulate matter formed to avoid blocking of the back pressure regulator. After the substrates were passed through the system, the outlet of the flow stream was directed into a receptacle where the excess carbon monoxide gas was vented off in the fume cupboard. The reaction mixture was then evaporated to dryness, ethyl acetate (25 mL) and sodium carbonate solution (2 M, 10 mL) were added and transferred to a separating funnel. After collecting the aqueous layer, the organic layer was extracted with sodium carbonate solution (2 M, 2 × 10 mL). The combined aqueous layers were acidified by the addition of 2 M HCl solution which was then extracted with ethyl acetate (3 x 25 mL). The organic layer was dried over sodium sulfate, and the solvent evaporated under vacuum to give the crude product as a solid. The crude product was then recrystallised from the appropriate solvent.
