Palladium-Catalyzed Aryl C−H Bonds Activation/Acetoxylation Utilizing a Bidentate System
摘要:
A palladium-catalyzed aryl C-H bonds activation/acetoxylation reaction utilizing a bidentate system has been explored. This transformation has been applied to a wide array of pyridine and 8-aminoquinoline derivatives and it exhibits excellent functional group tolerance.

A cobalt‐catalyzed sp2 C−H acetoxylation of amides having 8‐aminoquinoline as a directing group has been achieved using manganese(III) acetate both as an oxidant and an acetoxysource. Operational simplicity, broad range of functional group tolerance, use of an earth abundant first row transition metal, and, most importantly, exploitation of an unprecedented acetoxysource are the key features. The
