A new, general method for the synthesis of phenanthridines has been developed by palladium-catalyzedoxidative remote CH olefination–carboamination–CC bondcleavage tandem reaction. It is noteworthy that alkenes are used as the one-carbon resources for this tandem reaction.

‐Sulfonyl‐2‐aminobiaryls with [60]Fullerene through Sequential C‐H Bond Activation, C‐C and C‐N Bond Formation
An extraordinarily efficient hybrid acids‐assisted, palladium‐catalyzed and chelating‐group‐assisted CH bond activation of N‐sulfonyl‐2‐aminobiaryls and their annulations with [60]fullerene via sequential CC and CN bond formation at room temperature to afford [60]fulleroazepines is demonstrated. The formation of [60]fulleroazepines is highly regioselective and tolerant to both electron‐withdrawing
An efficient method for the construction of dibenzo[b,d]azepines containing two distinct stereogenic elements in a highly diastereoselective fashion is described. The key of the [5 + 2] reaction is to form a π-allylpalladium species through sequential C–H activation and regiospecific migratory insertion of the diene. This observation contrasts with the behavior of 1,2-alkenes that generally underwent

A palladium-catalyzed efficient C–H acylation reaction of biaryl-2-amines and aromatic aldehydes is developed. This dehydrogenativecross-coupling protocol could furnish monoacylation and diacylation products in moderate to good yields with a broad substrate scope and good regioselectivity.
