Cyclopentadiene production is usually not distinguished from dicyclopentadiene since they interconvert. They are obtained from coal tar (about 10–20 g/tonne) and by steam cracking of naphtha (about 14 kg/tonne). To obtain cyclopentadiene monomer, commercial dicyclopentadiene is cracked by heating to around 180 °C. The monomer is collected by distillation, and used soon thereafter. It advis… WebJan 5, 2016 · One of the bare minimum requirements for aromaticity is that besides being cyclic, and having 2n + 2 π electrons within the ring, the compound has to have electron delocalization all throughout the ring. Consider the structure of cyclobutene: That's all its π electrons can do, sadly.
