fluoride promoters on this process show that while electron-deficient arenes can undergo direct oxidation from the hydrosilane, electron-rich aromatics benefit from silane activation via oxidation to the methoxysilane using homogeneous or heterogeneous transition metal catalysis. The combination of these two oxidations into a streamlined flow procedure involving minimal processing of reaction intermediates
已经开发了快速,有效的方法来由芳基氢硅烷的氧化制备苯酚。芳烃取代基和氟化助催化剂对这一过程的影响表明,尽管缺电子的芳烃可从氢硅烷中直接氧化,但富含电子的芳烃可通过使用均相或非均相过渡金属催化氧化为甲氧基硅烷而从硅烷活化中受益。还报道了将这两种氧化结合成流线型流程,该流程涉及对反应中间体的最少处理。
