在四氢呋喃溶液中,由2,3-二溴-1,4-二氧杂环己烯经2-溴-3-锂-1,4-二氧杂环己烯在低温下合成了1,4-二氧杂环己炔,并分离得到相应的环三聚体三(亚乙二氧基)苯(1,2,3,4,5,6,7,8,9,10,11,12-十二氢-1,4,5,8,9,12-六氧杂苯并菲)。
1,4-Dioxacyclohexyne (p-dioxyne) has been generated at low temperature in tetrahydrofuran solution from 2,3-dibromo-1,4-dioxacyclohexene, via 2-bromo-3-lithio-1,4-dioxacyclohexene, and isolated as the corresponding cyclotrimer tris(ethylendioxy)benzene (1,2,3,4,5,6,7,8,9,10,11,12-dodecahydro-1,4,5,8,9,12-hexaoxatriphenylene).
