Abstract

Attempts to obtain 1, 2-diphenylcyclopentadiene led to its Diels–Alder dimer. Evidence for dissociation of this dimer has only been obtained in its reaction with molybdenum carbonyl. By contrast, 1, 4-dimethyl-2, 3-diphenylcyclopentadiene and 1, 2, 3-trimethyl-4, 5- diphenylcyclopentadiene exist as stable monomers, like all other di-and polyarylcyclopentadienes. Exact structures have been assigned to these and other ...
