5100-98-1, name is 3-Chloro-2-iodotoluene, belongs to iodides-buliding-blocks compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. SDS of cas: 5100-98-1

A 0.0757 M solution of P(/-Bu)3 in toluene (5.19 ml_, 0.393 mmol), a solution of 3-chloro-2- iodotoluene a112 (5.0 g, 19.8 mmol) in degassed toluene (10 ml.) and a solution of tert- butylacetate (2.53 g, 21.8 mmol) in degassed toluene (10 ml.) are sequentially added to a mixture of LiHMDS (7.60 g, 45.5 mmol) and Pd(dba)2 (0.226 g, 0.393 mmol) in degassed toluene (35 mL) under stirring in argon. The reaction mixture is stirred at room temperature for 2 h and decomposed by the addition of a saturated NH4CI solution (50 mL). After 15 min, the organic layer is separated, and the aqueous layer is subjected to extraction with diethylether. The combined organic extracts are dried over anhydrous Na2SC>4 and evaporated. The residue (6.38 g) is purified by chromatography on silicagel (petroleum ether/ AcOEt 10/1 v/v). The solvents are removed to afford tert-butyl (2-chloro-6- methylphenyl)acetate a113 as a light-yellow oil (4.80 g). Yield: 100 percent. GC-MS (M+- – (C4H8)): 184.

The synthetic route of 5100-98-1 has been constantly updated, and we look forward to future research findings.

5100-98-1, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 5100-98-1 name is 3-Chloro-2-iodotoluene, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.

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 ¡ãC, 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 ¡Á 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.

At the same time, in my other blogs, there are other synthetic methods of this type of compound, 3-Chloro-2-iodotoluene, and friends who are interested can also refer to it.
