摘要:P4S10和六甲基二硅氧烷的组合可将酯,内酯,酰胺,内酰胺和酮有效地转化为其相应的硫代衍生物.在元素硫的存在下,该试剂将3-氧代酯转化为二硫代硫酮.产率与使用劳森试剂获得的收率相当或更高.该方法的优点在于,可以通过简单的水解后处理或通过硅胶过滤而不是通过劳氏试剂所要求的色谱法来除去试剂衍生的副产物.

摘要:Esters of acrylic acid and methacrylic acid may be polymerized with the aid of either free radical forming or ionically effective initiators. The stereospecificy of the polymers may be influenced by the selection of specific initiators; magnesium-organic compounds are suitable for the synthesis of isotactic polymers. Acrylic acid and methacrylic acid esters having a high degree of isotacticity and a narrow molecular weight distribution are obtained with the aid of substituted phenylmagnesium halides. They are suitable as gauge and as test substances.
