Post-Functionalization of Organometallic Complexes via Click-Reaction

Molecules, 2022
CuAAC (Cu catalyzed azide-alkyne cycloaddition) click-reaction is a simple and powerful method for the post-synthetic modification of organometallic complexes of transition metals. This approach allows the selective introduction of additional donor sites
