‘Auto-click’ functionalization for diversified copper(i) and gold(i) NHCs†
Abstract
Azide-tagged CuI-NHC reacts in an ‘auto-click’ process to furnish complexes functionalized by 1,2,3-triazoles bearing diverse substituents. The resulting CuI complexes are amenable to further transmetallation to AuI. The whole strategy proceeds with mild conditions and constitutes an efficient entry to functionalised metal-NHCs with biorelevant moieties.
