Cobalt(III)-Catalyzed C–C Coupling of Arenes with 7‑Oxabenzonorbornadiene and 2‑Vinyloxirane via C–H Activation Lingheng Kong Songjie Yu Guodong Tang He Wang Xukai Zhou Xingwei Li 10.1021/acs.orglett.6b01806.s001 https://acs.figshare.com/articles/journal_contribution/Cobalt_III_-Catalyzed_C_C_Coupling_of_Arenes_with_7_Oxabenzonorbornadiene_and_2_Vinyloxirane_via_C_H_Activation/3474824 Co­(III)-catalyzed mild C–C couplings of arenes with strained rings such as 7-oxabenzonorbornadienes and 2-vinyloxirane have been realized. The transformation is proposed to undergo <i>ortho</i> C–H activation, olefin insertion, and subsequent β-oxygen elimination. A broad range of synthetically useful functional groups are compatible, thus providing a new entry to access diversely 2-functionalized indoles. 2016-07-08 13:38:31 diversely olefin insertion functionalized elimination Oxabenzonorbornadiene Activation access activation oxabenzonorbornadiene transformation Arene indole Vinyloxirane Co arene coupling vinyloxirane Cobalt ortho entry synthetically
