  Liquid sulfur as a reagent: synthesis of polysulfanes with 20 or more sulfur atoms with characterization by UPLC-(Ag⁺)-coordination ion spray-MS

  摘要：

  Diallyl disulfide reacts within minutes with liquid sulfur at 120 degrees C giving a family of diallyl polysulfanes, All(2)S(n) (n=322), characterized by ultra-performance liquid chromatography-(Ag+)-coordination ion spray-mass spectrometry (UPLC-(Ag+)CIS-MS). Similarly, garlic oil (GO), bis-(2-methyl-2-propenyl), bis-(2-chloro-2-propenyl), bis-(3-methyl-2-butenyl), and bis-(2-cyclohexen-1-yl) disulfides all give families of polysulfanes with up to 22 sequential sulfur atoms. New members of families of silver chelators with up to 10 sulfur atoms were found in GO using UPLC-(Ag+)CIS-MS.[GRAPHICS].

  在水中高效合成有机硫代乙酸酯

  摘要：

  硫代乙酸盐作为硫醇的前体是合成其他有机硫化合物的有趣起点。本文中，我们提出一种简单，有效和快速的方法，以水为溶剂获得有机硫代乙酸盐。考虑到过去几十年来对环境友好的合成方法的高度重视，我们证明了硫代乙酸根阴离子作为亲核试剂在水性介质中进行亲核取代反应的作用和强度。使用碳酸钾作为安全和温和的碱，在pH控制下进行反应以防止甲磺酸酯原料分解。简单的后处理即可获得具有优异收率和可接受纯度的产品。

  The reaction of allylic dienylic sulfone with dibromodifluoromethane in the presence of alumina-supported KOH in dichloromethane solution results in facile rearrangement affording the corresponding all-trans 1,3,5,7-octatetraenes in excellent yields. This result shows that the double bonds of stereochemically defined allylic dienylic sulfone retain their stereochemistry and the newly formed double
