|Section2= |Section7= |Section8= }} 1,4-Dioxin (also referred as dioxin or ''p''-dioxin) is a heterocyclic, organic, non-aromatic〔Science of Synthesis: Houben-Weyl Methods of Molecular Transformations Vol. 16: Six-Membered Hetarenes with Two Identical Heteroatoms〕 compound with the chemical formula C4H4O2. There is an isomeric form of 1,4-dioxin, 1,2-dioxin (or ''o''-dioxin). 1,2-Dioxin is very unstable due to its peroxide-like characteristics. The term “dioxin” is most commonly used for a family of derivatives of dioxin, known as polychlorinated dibenzodioxins (PCDDs). ==Preparation== 1,4-Dioxin can be prepared by cycloaddition, namely by the Diels–Alder reaction of furan and maleic anhydride. The adduct formed has a carbon-carbon double bond, which is converted to an epoxide. The epoxide then undergoes a retro-Diels–Alder reaction, forming 1,4-dioxin and regenerating maleic anhydride. 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「1,4-Dioxin」の詳細全文を読む スポンサード リンク
