Abstract
Transition-metal-catalyzed functionalizations of C–H bonds to construct C–C bonds
represent an ideal route in the synthesis of valuable organic molecules. In particular,
rhodium(III)-catalyzed C–H bond activation offers an attractive strategy due to its
efficiency and step economy for direct functionalization in organic synthesis. Consequently,
recent developments in this area have assured a high level of regioselectivity in
C–H functionalization reactions. In this Account, we have summarized our recent achievements
in the functionalizations of sp2- and sp3-C–H bonds using rhodium catalyst. The scope, limitation, and mechanism of these reactions
have been described briefly.
