Internal 2D networking of silver bromide with a bidentate N-heterocyclic carbene ligand enables the formation of an inherently heterogeneous reusable catalyst for multicomponent A3 coupling

Abstract

We report the synthesis of an internal 2D networking heterogeneous silver catalyst stabilized by bidentate N-heterocyclic carbene ligands. The Ag–NHC catalyst is employed in A3 coupling reactions and demonstrated reusability for six cycles.
