Cyclic homoconjugated oligodiacetylenes, consisting of butadiyne subunits interconnected with two different sp-linkers in alternation, were synthesized by coupling of different 1,4-pentadiyne synthons. The "exploded" [4]pericyclyne 7 was obtained in a "one-pot" random cyclodehydro-oligomerization reaction, by cross-coupling of two different 1,4-pentadiyne units. Larger ring structures such as the C macrocyclic [6]pericyclyne 22 and the unsymmetrically diynetetrayne expanded C-[4]pericyclyne 27 afforded a stepwise approach. Heterocoupling of two different 1,4-pentadiynes in a molecular ratio of 1:2 and 2:1 afforded the symmetrical pentadecahexaynes 12 and 20, respectively. Cyclodehydrodimerization gave the symmetrically patterned cyclotriacontadodecayne 22. A collective heterocoupling of two different 1,4-pentadiynes with TIPS-acetylene resulted in the formation of acyclic dodecapentayne 26. Final cyclodimerization yielded the cyclotetracosadecayne 27.
