Reference of 402-43-7, The chemical industry reduces the impact on the environment during synthesis 402-43-7, name is 1-Bromo-4-(trifluoromethyl)benzene, I believe this compound will play a more active role in future production and life.

General procedure: Aniline ligand (10.0mmol) and palladium dichloride (0.886g, 5.0mmol) were dissolved in 15mL of DMAc at room temperature. After the mixture was stirred for 0.5hat 80C, the methanol (50mL) was added and the precipitation was formed. The precipitate of palladium complexes was then dissolved in 5mL dichloromethane, then 20mL hexane was added. After crystallized from the mixture of ethanol and dichloromethylene, the palladium complex was obtained as light yellow crystals.

In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 1-Bromo-4-(trifluoromethyl)benzene, other downstream synthetic routes, hurry up and to see.

Application of 402-43-7, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 402-43-7, name is 1-Bromo-4-(trifluoromethyl)benzene belongs to bromides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.

General procedure: In an undivided cellequipped with a Zn sacrificial anode (1.5 x 1.0 cm2) and a Pt cathode (1.5 x 1.0 cm2) was placed a DMF(3 mL) solution of 4-bromopropiophenone (4a, 0.053 g, 0.25 mmol), 1 (0.14 g, 7.6 x 10-2 mmol),[Bu4N+][Tf2N-] (0.16 g, 0.30 mmol), and a catalytic amount of PdCl2(PPh3)2 (0.0086 g, 1.2 x 10-2 mmol).The solution was electrolyzed under constant current conditions (10 mA) at 60 C until 2 F/mol-4a ofelectricity was passed. The reaction mixture was poured into 5% aq. HCl (12 mL). The mixture wasextracted with AcOEt (10 mL x 3). The combined organic layer was washed successively with waterand brine, dried (Na2SO4), and concentrated under reduced pressure. The residue was purified bycolumn chromatography (SiO2, toluene/AcOEt = 10/1) to afford 4,4?-dipropanoylbiphenyl (5a, 0.030 g,0.11 mmol, 89%).

The synthetic route of 1-Bromo-4-(trifluoromethyl)benzene has been constantly updated, and we look forward to future research findings.

402-43-7, 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 402-43-7 as follows.

General procedure: Na2CO3 (212 mg, 2 mmol), 4-chloronitrobenzene (1 mmol) and styrene (1.5 mmol) were added successively into a dried Schlenk tube under nitrogen. Then the DMA (0.1 mL) solution of DADPP (0.002 mmol) and [Pd(C3H5)Cl]2 (0.0005 mmol), which was reacted at 100 C for 10 min prior to use, was added into the mixture. The reaction was performed at 130 C. At the end of reaction, the mixture solution was extracted with ethyl acetate (3 ¡Á 5 mL). Combined organic phase was washed with brine (3 ¡Á 5 mL) and dried over MgSO4. The dried solution was filtered and purified with silica gel chromatography (petroleum ether 60-90 C) to give a corresponding product.

According to the analysis of related databases, 402-43-7, the application of this compound in the production field has become more and more popular.
