Application of 138526-69-9,Some common heterocyclic compound, 138526-69-9, name is 1-Bromo-3,4,5-trifluorobenzene, molecular formula is C6H2BrF3, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
General procedure: A mixture of the styrene (3 mmol), the halogenated benzene (3 mmol), triethanolamine (3 mmol) and Pd(II) acetate (0.03 g) was stirred under argon at 100 C for 24 h. The reaction was cooled to 25 C, quenched by the addition of dil. aq. hydrochloric acid (2 N, 10 ml), and extracted with ether (3 × 100 ml). The organic phases were dried (Na2SO4), the solvents evaporated, and the crude product subjected to chromatography (silica gel, hexane/ethyl acetate mixtures).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 1-Bromo-3,4,5-trifluorobenzene, its application will become more common.
