It is an isomeric form of 1,4-dioxin (or p-dioxin). Due to its peroxide-like characteristics, 1,2-dioxin is very unstable and has not been isolated. Calculations suggest that it would isomerize rapidly into but-2-enedial.Matsumoto M. https://books.google.com/books?id=Ah6GAwAAQBAJ&pg=PA13 Science of Synthesis: Houben-Weyl Methods of Molecular Transformations Vol. 16: Six-Membered Hetarenes with Two Identical Heteroatoms Georg Thieme Verlag 2014 9783131718815 13 Product Class 1: 1,2-Dioxins and Benzo- and Dibenzo- Fused Derivatives 2020-06-12 Even substituted derivatives, such as 1,4-diphenyl-2,3-benzodioxin, are very labile. 10.1021/ja00368a021 Chemiluminescence of organic peroxides.

It was subsequently shown that the initial compound was not a derivative of 1,2-dioxin, but a thermodynamically more stable dione. 10.1021/jo034305i 12737603 Revised Structure of a Purported 1,2-Dioxin: A Combined Experimental and Theoretical Study The Journal of Organic Chemistry 68 10 4108–11 2003 Block Eric Shan Zhixing Glass Richard S.
