Electric Literature of 722-92-9, Adding some certain compound to certain chemical reactions, such as: 722-92-9, name is 2-(4-Aminophenyl)-1,1,1,3,3,3-hexafluoropropan-2-ol,molecular formula is C9H7F6NO, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 722-92-9.
11091] To a solution of 2-(4-aminophenyl)-1,1,1,3,3,3- hexafluoropropan-2-ol (2.50 g, 9.64 mmol) (preparation, for example, W. A. Sheppard, J Am. Chem. Soc. 1965, 87, 24 10-2420) in glacial acetic acid (40 ml) was added, at RT, N-chlorosuccinimide (2.71 g, 20.2 mmol). The mixture was stirred at 75° C. for 3 h and then at RT for 14 h. Subsequently, the mixture was added to water and extracted with EtOAc. The organic phase was washed with water and saturated aqueous NaHCO3 solution and dried over magnesium sulphate. Afier solvent had been removed, the residue was taken up in MTI3E and the solids were filtered off. The filtrate was concentrated under reduced pressure and the crude product was purified by means of column chromatography on 5i02 (n-hexane/EtOAc gradient). 2.89 g (91percent) of 2-(4-amino-3,5-dichlorphenyl)- 1,1,1 ,3,3,3-hexafluoropro- pan-2-ol were obtained.11092] HPLCMSa): log P=3.04, mass (m/z)=328 [M+H].11093] ?H NMR (400 MHz, d3-acetonitrile): oe=5.13 (br s, 2H), 6.02 (br s, 1H), 7.51 (s, 2H).
According to the analysis of related databases, 722-92-9, the application of this compound in the production field has become more and more popular.
