Intramolecular Direct C–H Arylation via a Metallocenic Radical Pathway: Stereospecific Approach to Planar-Chiral Ferrocenes

Intramolecular Direct C–H Arylation via a Metallocenic Radical Pathway: Stereospecific Approach to Planar-Chiral Ferrocenes
Zhong Jin, Xiaohua Xu, Yang Liu, Jiancong Xu, Jinling Zhang
Transition metal-free synthesis of planar-chiral 1,2-fused ferrocenes via intramolecular direct C–H bond arylation was achieved. The C–H arylation reactions promoted by a catalytic amount of 1,10-phenanthroline highlighted a unique planar-chiral metallocenic radical intermediate, generated from iodoferrocenes via a single-electron transfer process.
