We report the one-step synthesis of diversely substituted functional 1,2-dithiolanes by reacting readily accessible 1,3-bis-tert-butyl thioethers with bromine. The reaction proceeds to completion within minutes under mild conditions, presumably via a sulfonium-mediated ring closure. Using X-ray crystallography and UV-vis spectroscopy, we demonstrate how substituent size and ring substitution pattern
我们报道了通过容易获得的 1,3-双叔丁基硫醚与溴反应,一步合成了多种取代的功能性 1,2-二硫杂环戊烷。该反应在温和条件下在几分钟内完成,大概是通过锍介导的闭环。使用 X 射线晶体学和紫外可见光谱,我们证明了取代基大小和环取代模式如何影响 1,2-二硫戊环的几何形状和光物理性质。

Abstract 2-Substituted epichlorohydrins have been synthesized by starting with 1,2-dichloro acetone and various alkyl and aryl halides via dichlorohydrins followed by cyclization. The reactive 2-substituted epichlorohydrins were subjected to nucleophilic attacking of azide and cyanide ions to afford corresponding β-azido alcohols and α,β-unsaturated nitriles.
