As a continuation of recent study on the synthesis of a bis[1,4]oxathiinodipyridine ring system, we would now like to report the preparation of 7-chlorobenzo[1″,2″:5,6:3″,4″:5′,6′]-bis[1,4]oxathiino[3,2-b: 3′,2′-b]dipyridine. Although a potentially complex reaction with several products possible, the title compound was formed exclusively, suggesting considerable mechanistic selectivity. The characterization
作为对合成双[1,4]氧杂萘并二吡啶环系统的最新研究的继续,我们现在要报告制备7-氯苯并[1“,2”:5,6:3“,4”的方法: 5′,6′]-双[1,4]氧杂噻吩并[3,2- b:3′,2′- b ]二吡啶。尽管可能与几种产物发生潜在的复杂反应,但仅形成了标题化合物,表明具有相当高的机械选择性。还报道了通过FT - 1 H-nmr对产物的表征及其质谱碎裂途径。
