Pronunciation: [fˈʊlviːn] (IPA) 
The word "fulvene" is spelled with a "u" and "e" at the end to indicate its chemical structure. The IPA phonetic transcription of "fulvene" is /ˈfʊlvɛn/ with the stress on the first syllable. The "fulv" sound is pronounced as in "full" and the "ene" sound is pronounced as in "pen". Fulvene is a five-membered aromatic ring with a double bond and a carbonyl group, making it an important intermediate in organic chemistry.
Fulvene is a noun that refers to a compound with a specific molecular structure consisting of a bicyclic carbon ring accompanied by two double bonds. This structure is composed of five carbon atoms and one oxygen atom, with alternate single and double bonds between them. The double bonds located outside the ring make fulvene highly reactive and prone to participating in various chemical reactions.
Fulvene is further classified as an aromatic compound due to its distinctive ring structure and the presence of delocalized electrons, which contribute to its stability. The name "fulvene" is derived from the words "fulvalene" and "benzene," as it possesses a combination of characteristics from both compounds.
Given its unique structure, fulvene displays several intriguing properties that make it useful in numerous applications. It has shown potential in organic synthesis as a versatile building block for creating various chemical structures. Fulvene derivatives have been studied for their potential in drug discovery and medicinal chemistry, as they possess interesting biological activities.
In addition, fulvene derivatives have been investigated for their potential in materials science, particularly for their optoelectronic properties. These compounds have exhibited promising properties as components in electronic devices such as organic light-emitting diodes (OLEDs) and organic semiconductors.
In summary, fulvene is a chemical compound with a distinctive and reactive molecular structure involving a bicyclic ring and double bonds. Its unique properties and potential applications in organic synthesis, drug discovery, medicinal chemistry, and materials science make it a subject of great interest and study in various scientific fields.
The word fulvene is derived from the name of a compound called fulvalene, which was coined by American chemist Robert Burns Woodward in 1967. Woodward combined the term fulvalene from the Latin words fulvus (meaning yellow-brown) and valens (meaning to be powerful or strong). This name was chosen as a description of the compound's yellowish-brown color and its stability. Fulvene is a closely related compound that derives its name by replacing the alene ending with ene.
