Extracurricular laboratory: Synthetic route of 260355-20-2

The synthetic route of 260355-20-2 has been constantly updated, and we look forward to future research findings.

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. 260355-20-2, name is 1-Chloro-4-iodo-2-(trifluoromethyl)benzene, A new synthetic method of this compound is introduced below., Safety of 1-Chloro-4-iodo-2-(trifluoromethyl)benzene

[Reference Example 1] 4-chloro-3-trifluoromethyl-1-(1-trifluoromethylethenyl) benzene In a nitrogen atmosphere, to 53 mL of a 1M tetrahydrofuran solution of 1-trifluoromethylethenyl zinc bromide prepared according to a method described in the literatures, 7.1 g of 2-chloro-5-iodobenzotrifluoride and 0.65 g of dichlorobis(triphenylphosphine) palladium (II) were added and the resultant mixture was stirred while heating the mixture to reflux for 2.5 hours. After the completion of the reaction, the reaction mixture was left to be cooled down to room temperature and 200 mL of hexane was added to the reaction mixture, followed by filtering off the deposited insoluble substance. The resultant filtrate was washed with water (50 mL*1) and then dehydrated and dried over saturated saline and anhydrous sodium sulfate in this order and the solvent was distilled off under reduced pressure. The resultant residue was purified by silica gel column chromatography eluding with hexane to obtain 4.8 g of the objective substance as a colorless oily substance. 1H NMR (CDCl3, Me4Si, 300 MHz) delta 7.75 (s, 1H), 7.57 (d, J=8.8 Hz, 1H), 7.54 (d, J=8.8 Hz, 1H), 6.08 (s, 1H), 5.84 (s, 1H).

The synthetic route of 260355-20-2 has been constantly updated, and we look forward to future research findings.

In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 260355-20-2 as follows. SDS of cas: 260355-20-2

General procedure: reaction vial (8 ml) was charged with benzoazine (0.10 mmol, 1.0 equiv.), template-MeCN (0.10 mmol, 1.0 equiv.) and 0.2 ml dichloromethane. The mixture was stirred for 5 min at room temperature, and then concentrated in vacuo. Pd(OAc)2 (2.2 mg,10 mumol, 10 mol%), Ac-Gly-OH (2.3 mg, 20 mumol, 20 mol%), aryl iodide (0.3 mmol,3 equiv.), AgOAc (50 mg, 0.30 mmol, 3.0 equiv.), Ag2CO3 (27.6 mg, 0.1 mmol,1.0 equiv.), NBE-CO2Me (22.8 mg, 0.15 mmol, 1.5 equiv.) and HFIP (1.5 ml) were added. The reaction vial was sealed and allowed to stir at 80 C for 18 h. The reaction mixture was cooled to room temperature. Then a solution of DMAP (36.7 mg, 0.3 mmol, 3 equiv.) in toluene (1.5 ml) was added. The mixture was stirred at 80 C for 15 min. The reaction mixture was cooled to room temperatureand diluted with EtOAc. The mixture was filtered through a short pad of celite and eluted with EtOAc (2 ¡Á 2 ml). The filtrate was evaporated under reduced pressure. (If the product release was not complete, a solution of DMAP (18.4 mg,0.15 mmol, 1.5 equiv.) in toluene (1.5 ml) was added; the solution was then stirredat 80 C for 15 min and then concentrated.) Purification by preparative thin-layer chromatography afforded the title compound

According to the analysis of related databases, 260355-20-2, the application of this compound in the production field has become more and more popular.
