Polyquinane
A polyquinane or polyquinene is a saturated or unsaturated, respectively, polycyclic hydrocarbon consisting of fused five-membered rings.[1] The simplest member is the bicyclic compound bicyclo[3.3.0]octane. Other members are triquinacene and dodecahedrane.
Triquinacene
The compound triquinacene (tricyclo[5.2.1.-04,10]deca-2,5,8-triene) is the second member of a family of polyquinenes. It was synthesized in 1964 in the group of R. B. Woodward[2] in connection with its suspected homoaromatic properties (although it was found to have no such properties), and also as part of a failed attempt to synthesize the then-elusive and much-coveted compound dodecahedrane. Unlike the related pentacene, triquinacene is stable, and has a melting point of 18°C. The final step of its synthesis is a Cope elimination.
