the central acidic hydrogens of bis(methylsulfonyl)methane as a thioether followed by formation of the dianion and selective alkylation of the methyl group. Alkylation of one of the methyl groups was demonstrated as well as alkylation of both methyl groups with the same or different alkyl groups. Removal of the thioether moiety furnished the desired substituted disulfones.
据报道,合成宝石-二砜的简单有效的方法。该方法基于保护双(甲基磺酰基)甲烷的中心酸性氢之一作为硫醚,然后形成二价阴离子和甲基的选择性烷基化。证明了甲基之一的烷基化以及两个甲基具有相同或不同烷基的烷基化。除去硫醚部分提供了所需的取代的二砜。
