摘要：
We report here an efficient route to the synthesis of highly fluorescent hexaaryl[3]radialenes using the oligomerization of ate-type copper carbenoids, followed by cyclization with hexamethylditin and Pd(PPh3)(4); the structures of the [3]dendralene and hexaaryl[3]radialenes were determined by X-ray crystallographic analysis.
