Related Products of 89523-51-3,Some common heterocyclic compound, 89523-51-3, name is 5-Bromobenzo[c]phenanthrene, molecular formula is C18H11Br, 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.
Under an argon atmosphere, 3.07g of the 5-bromobenzo[c]phenanthrene which had been prepared in Synthesis Example 1, 4.18g of 10-(2-naphthyl)anthracene -9-boronic acid which had been synthesized by a known method, 0.231 g of tetraxis(triphenylphosphine)palladium(0), 40 mL of toluene and 20 mL of a 2M aqueous solution of sodium carbonate were charged. The resultant was refluxed with stirring for 8 hours. After cooling to room temperature, the reaction solution was extracted with toluene. An aqueous phase was removed, and an organic phase which had been separated was washed with water and saturated brine sequentially, and then dried with magnesium sulfate. After the magnesium sulfate was filtered out, the organic phase was concentrated. The resulting residue was purified by a silica gel column chromatography, whereby 4.13g of pale yellow crystals were obtained. As a result of mass spectrometry, the resulting crystals were confirmed to be the above-mentioned compound 1. The compound 1 had an m/e value of 530 with respect to a molecular weight of 530.20.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 5-Bromobenzo[c]phenanthrene, its application will become more common.
