‘Auto-click’ functionalization for diversified copper(<scp>i</scp>) and gold(<scp>i</scp>) NHCs

Abstract

Azide-tagged Cu(I)-NHC reacts in an 'auto-click' process to furnish complexes functionalized by 1,2,3-triazoles bearing diverse substituents. The resulting Cu(I) complexes are amenable to further transmetallation to Au(I). The whole strategy proceeds with mild conditions and constitutes an efficient entry to functionalised metal-NHCs with biorelevant moieties.
