The present feature article describes the different organocatalytic routes for the synthesis of substituted 1,2,3-triazoles.

The ease of anchoring single atoms on the g-C ₃ N ₄ matrix, through its abundant nitrogen sites, facilitates a variety of single atom catalysts for applications in multiple domains of catalysis.

The past three decades have witnessed extensive research in developing a range of non-metallic fused heterocyclic organic dyes for dye sensitized solar cells (DSSCs).

An unprecedented approach that enables the direct and selective preparation of 1,5-disubstituted 1,2,3-triazoles from abundantly available building blocks such as primary amines, enolizable ketones and 4-nitrophenyl azide as a renewable source of dinitrogen via an organocascade process has been developed. Furthermore, this efficient methodology also enables the synthesis of fully functionalized and fused N-substituted heterocycles.
