An efficient zeolite supported copper dual-atom catalyst for C–H amination of indoles has been developed for the green synthesis of 3-diarylaminoindoles.

An efficient intermolecular CÀ H aminohalogenation of indoles with azoles and NXS (X = F, Cl, Br, I) has been developed. This mild protocol provides a straightforward entry to structurally valuable 2-azolyl-3-halogenated indoles in one single operation. In addition, this attractive route for the synthesis of polyfunctionalized indoles is of great significance due to the product's versatile reactivity for further transformations.
