A palladium-catalyzed annulative π-extension reaction
of
bay-iodinated triphenylenes with aryl iodides/o-chloroaromatic
carboxylic acids was developed. This approach enabled the synthesis
of diverse polycyclic aromatic compounds, including dibenzo[fg,op]tetracenes, azadibenzo[fg,op]tetracenes, and tribenzo[a,g,m]coronenes. Initial studies indicate
that the resulting product, 2,3,8,9,14,15-hexakis(decyloxy)tribenzo[a,g,m]coronene, exhibits
good liquid-crystalline properties.
