Fulvene

Fulvene (pentafulvene) is a hydrocarbon with the formula (CH=CH)2C=CH2. It is a prototype of a cross-conjugated hydrocarbon.[2] Fulvene is rarely encountered,[3] but substituted derivatives (fulvenes) are numerous. They are mainly of interest as ligands and precursors to ligands in organometallic chemistry.
