RuII‐Catalysed Regioselective C–N Bond Formation of Indolines and Carbazole with Acyl Azides

Ru II ‐catalysed pyrimidine directed coupling of the C‐7 C–H bond of indolines with acyl azides as a nitrogen surrogate has been developed to produce acyl amides at room temperature. The reaction of aryl, heteroaryl and α,β‐unsaturated acyl azides can be accomplished in good yields. The procedure can be extended to the C1‐amidation of carbazole with moderate yields. The substrate scope, use of less expensive Ru‐catalysis, and oxidant‐free conditions are the significant practical features.
