Abstract

The copper(I)‐catalyzed dipolar [2+3] cycloaddition reaction of an azide and a terminal alkyne is exploited in the preparation of various europium(III), terbium(III), and dysprosium(III) chelates (Schemes 1–3). By changing the nature of the alkyne and the azide, a wide range of chelates and biomolecule‐labeling reactants were obtained. The photophysical properties (Table) of the synthesized chelates are also discussed.
