Abstract

Copper(I)-catalysed azide–alkyne cycloaddition (CuAAC) has been successfully conducted under reductant-free conditions. The catalytic system consisted of a combination of a copper(I)–N-heterocyclic carbene complex and aromatic N-donors. The catalyst is stable and can be stored, thus rendering the reaction valuable for routine use.
