components were prepared for ligand acceleration of the copper-catalyzed azide-alkynecycloaddition reaction. Two classes of ligands were identified: those that give rise to high reaction rates in coordinating solvents but inhibit the process when used in excess relative to copper and those that provide for fast catalysis in water and are not inhibitory in excess. Several "mixed" ligands were identified that
