One-pot synthesis of sterically congested large aromatic hydrocarbons via 1,4-diphenyl-2,3-triphenylyne.

Large polyarenes with unusually complex structures can be obtained in a straightforward manner from commercially available starting materials, by means of aryne chemistry. This approach involves a sequence of tandem reactions that can be performed in one pot to give sterically congested chiral aromatic hydrocarbons that adopt highly twisted conformations.
