Title
Palladium catalyzed C5-arylation of 2-fused triazole substituted thiophene and furan using aryl iodide through CH activation strategy
Abstract

•Pd-catalyzed CH activation of heteroarene with fused 1,2,4-triazole is described.•Aryl/heteroaryl iodides are used as an arylating partner.•C-5 regioselective arylation at thiophene/furan is observed.•Nitrogens present in the fused 1,2,4-triazole are not directing the arylation.

Pd-catalyzed arylation of 2-fused triazole substituted thiophene and furan using aryl iodide through CH activation is reported. It is found that the arylation occurs selectively at C-5 position of the thiophene and furan. Moreover, the nitrogens in the fused 1,2,4-triazole core were assisting neither N-directed arylation nor arylation in the triazole.
