two-step procedure for the site-specific preparation of fluorinated naphthalene and phenanthrene derivatives is described. The Sonogashira reaction of bromofluoro-substituted alkenes with terminal alkynes, followed by base-catalyzed cyclization in refluxing N-methyl-2-pyrrolidinone (NMP), affords the corresponding fluorinated naphthalene and phenanthrene derivatives in good yields.
描述了一种用于现场具体制备氟化萘和菲衍生物的简便的两步程序。溴氟取代的烯烃与末端炔烃的Sonogashira反应,然后在回流的N-甲基-2-吡咯烷酮(NMP)中进行碱催化的环化反应,以良好的收率得到相应的氟化萘和菲衍生物。
