A new kind of intermolecular indole C-H amidation reaction catalyzed by the most frequently used palladium catalyst has been developed. Sulfonyl azide was employed as an innovative nitrogen source and environmentally benign nitrogen was produced as the only byproduct.

their synthesis by modern catalytic methods. This full paper presents the development and extended scope of the new cyclization methodology. The transformation of the products into fused bis‐indoles is also demonstrated along with the discovery of an unusual palladium‐catalyzed reductive biphenyl coupling reaction. The titanium(III)‐catalyzed cyclization has also been applied to the synthesis of substituted
