Electric Literature of 623-00-7, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 623-00-7, name is 4-Bromobenzonitrile, This compound has unique chemical properties. The synthetic route is as follows.
General procedure: In a 25mL round bottom flask containing 5mL of ethyleneglycol, aryl halide (1 equiv), trimethoxyphenylsilane (1.5equiv), NaOH (3 equiv) and Pd NPs (0.2mol%) were takenand stirred at 100C for required time. The reaction masswas cooled to room temperature after reaction completion(as monitored by TLC), followed by the recovery of Pd NPsby centrifugation at 6000rpm for 30min. The product wasthen extracted using dichloromethane (2 ¡Á 20mL) and subjectedto water wash (1 ¡Á 20mL) and brine wash (1 ¡Á 20mL)followed by drying of the organic layer over Na2SO4.Thedried organic layer was concentrated in vacuo, and the productwas purified by column chromatography using n-hexaneand ethyl acetate as eluents to aford the corresponding productsin good to excellent yields. All the coupled productswere known molecules and were confirmed by comparingthe melting point, 1H NMR and LC-MS data with authenticsamples (see Supporting Information for details).
The chemical industry reduces the impact on the environment during synthesis 4-Bromobenzonitrile. I believe this compound will play a more active role in future production and life.
