Synthesis of valuable terpyridine building blocks to generate a variety of metallodendrons by the convergent approach

Efficient strategies for the synthesis of three building-blocks 4′-(functionalized)-2,2′:6′,2″-terpyridine have been developed for the convergent synthesis of metallodendrons; these strategies provide a practical approach for the rational design of highly conjugated metallodendrimers.

Graphical abstractWe report the synthesis of dendrons and metallodendrons bearing adapted functional pendant groups that make them valuable building blocks for the straightforward synthesis of fully conjugated metallodendrimers using the Sonogashira cross-coupling reaction.Figure optionsDownload full-size imageDownload as PowerPoint slide
