<p>➀ Researchers at the Institute of Organic Chemistry, University of Vienna, have presented an innovative approach to the synthesis of Azaparacyclophanes (APCs), a class of highly developed ring-shaped molecular structures with great potential for materials science.</p><p>➁ The new CTM method uses the 'Pd-catalyzed Buchwald-Hartwig cross-coupling reaction' to create π-conjugated cyclic structures, offering a direct and efficient way to produce APCs.</p><p>➂ The method is flexible, allowing the production of APCs with different ring sizes and functional groups, and is scalable and reproducible.</p>
