Such compounds are intermediates in many catalytic reactions that convert alkenes to other organic products, e.g. hydrogenation, hydroformylation, and polymerization.〔Elschenbroich, C. ”Organometallics” (2006) Wiley-VCH: Weinheim.

The bonding between alkenes and transition metals is described by the Dewar-Chatt-Duncanson model, which involves donation of electrons in the pi-orbital on the alkene to empty orbitals on the metal. This interaction is reinforced by back bonding that entails sharing of electrons in other metal orbitals into the otherwise empty pi-antibonding level on the alkene. Mono- and diolefins are often used as ligands in stable complexes. Cyclooctadiene and norbornadiene are popular chelating agents, and ethylene itself is sometimes used as a ligand, for example, in Zeise's salt. In addition, metal–alkene complexes are intermediates in many metal-catalyzed reactions including hydrogenation, hydroformylation, and polymerization. ==References== 〔 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「Transition metal alkene complex」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
