日期:——
ortho-functionalization of pentafluorosulfanyl arenes has been developed. ortho-Lithiation with lithium tetramethylpiperidide at −60 °C in the presence of silicon, germanium, and tin electrophiles affords trapped products in moderate to highyields. Precise temperature regimes and the presence of electrophiles during lithiation are important for successful reactions, since the pentafluorosulfanyl group
已经开发了一种用于五氟硫烷基芳烃的邻位官能化的通用方法。邻-在硅、锗和锡亲电子试剂存在下,在 -60 °C 下用四甲基哌啶锂进行锂化,以中等至高产率提供捕获的产物。锂化过程中精确的温度范围和亲电试剂的存在对于成功的反应很重要,因为五氟硫烷基在高于 -40 °C 的温度下充当有能力的离去基团。氟、溴、碘、可烯醇化的酮、氰基、酯、酰胺和未取代的氨基官能团与反应条件相容。还证明了 2-二甲基甲硅烷基五氟硫烷基苯转化为 2-卤代衍生物,可用作交叉偶联化学中的起始材料。
