Realized C–H Functionalization of Aryldiazo Compounds via Rhodium Relay Catalysis
摘要:
An unprecedented C-H functionalization of aryldiazo compounds without a preinstallation of directing group has been realized under mild conditions, which differs from former reports in its use of diazo compounds as coupling partners in directed C-H activations. This novel transformation has been realized by a rhodium self-relay catalysis, a tandem process of the in situ formation of a directing group and sequential C-H bond activation.
