carbene catalytic systems for the intramolecular decarbonylative coupling through the chelation-assisted C−C bond cleavage of acylindoles and diarylketones. The reaction tolerates a wide range of functional groups such as alkyl, aryl, and heteroaryl groups, giving the decarbonylative products in moderate to excellent yields. This transformation involves the cleavage of two C−C bonds and formation of

A RhI‐catalyzed direct C2‐arylation of indoles with diversely substituted arylcarboxylicacids has been developed using 2‐pyrimidyl group as an easily installable and readily removable N‐directing group. The reaction proceeded smoothly without the need for any external oxidants under relatively mild conditions to produce the C2‐arylated indoles in high yields with excellent regioselectivity. A range
