Heterogeneous Catalytic Reactions On Water by Using Stable Polymeric Alkynylcopper(I) Pre-Catalysts: Alkyne/Azide Cycloaddition Reactions

Dinuclear alkynylcopper(I) complexes have been found to be the active pre-catalysts in copper-catalysed cycloaddition of azides and terminal alkynes (CuAAC). These copper(I) ladderane polymers are used in on water CuAAC reactions, with loadings as low as 1 mol-%.
