|Section2= |Section3= }} Fulvene is one of several hydrocarbons with the same formula as benzene, C6H6. The fulvenes are the class of molecules based on this simple hydrocarbon skeleton; the parent chemical, fulvene itself, is rarely encountered. Thiele is credited with discovering the scope of the reaction between cyclopentadiene and aldehydes and ketones that yields the brightly coloured fulvene derivatives. Most fulvenes are still prepared by this route, starting from cyclopentadiene or its sodium cyclopentadienyl anionic form. ==Ligand in organometallic chemistry== 2,3,4,5-Tetramethylfulvene, abbreviated Me4Fv, is a relatively common ligand in organometallic chemistry. It typically results from the deprotonation of cationic pentamethylcyclopentadienyl complexes. Some Me4Fv complexes are called tuck-in complexes. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Fulvene」の詳細全文を読む スポンサード リンク
