| Outline of Final Research Achievements |
[2+2+2] Cycloaddition is an atom-economical protocol for the synthesis of compounds possessing six-membered ring system, and many examples of cyclotrimerization of alkynes for the construction of benzene ring have been reported. On the other hand, hexaealkynylbenzenes are very useful compounds owing to their unique properties as organic electronics materials, such as liquid crystals and nonlinear optical materials. However, most of the preported protocols required multi steps along with the formation of by-products. Therefore, I developed the synthesis of hexaethynylbenzenes by [2+2+2] cycloaddition of 1,3,5-hexatriynes.
