Abstract Copper-catalyzed aerobic methyl/methylene oxygenation of substituted indoles and pyrroles was developed using 1,4-diazabicyclo[2.2.2]octane (DABCO) as an additive in dimethyl sulfoxide (DMSO). Similar aerobic catalytic conditions could also be utilized for direct C–H formylation of C(3) on indoles and C(2) on pyrroles.

The palladium‐catalyzed addition of indoles to nitriles affords 3‐acylindoles. The reaction proceeds with high selectivity, wide substrate scope, broadly available starting materials, and an operationally simple procedure. Combination with the palladium‐catalyzed intramolecular oxidative coupling of 3‐indolylarylketone gives access to indenoindolones in a one‐pot synthesis.
