C–O activation and its application have drawn much attention since oxygen-based electrophiles are easily available, less toxic, and more environmentally benign. This letter presents systematically results on the Ni-catalyzed Kumada–Tamao–Corriu coupling based on siloxy arenes/alkenes, which provides a new strategy of silyl protection/C–C bond formation sequence in organic synthesis.
C–O 激活及其应用引起了广泛关注,因为以氧为基础的亲电试剂易于获得、毒性较低,并且对环境更友好。本文系统地展示了基于硅氧芳烃/烯烃的镍催化 Kumada–Tamao–Corriu 交联反应的结果,为有机合成提供了一种新的硅保护/C–C 键形成序列策略。
