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