(equation presented) This Letter describes the synthesis of the first macrobicyclic subunits of the hypothetical all-carbon network graphyne. Key to synthetic success is an intramolecular Sonogashira cross-coupling sequence.
It takes alkynes to make a world - New methods for dehydrobenzoannulene synthesis

Recent advances in the assembly of dehydrobenzoannulenes (DBAs) are the subject of this account. Using in situ generated acetylenic intermediates, novel α,ω-polyynes can be easily constructed using Pd-catalyzed alkynylation methodology. Subsequent cyclization via intra- and intermolecular Cu-mediated reactions can provide a wide variety of DBAs, including heretofore inaccessible topologies, systems with an unprecedented number of acetylenic linkages, structures with derivatized aromatic rings, and unusual organometallic species.
