  to the α atom of alkyl sulfones. In this paper, a new ionic chlorination method of alkyl sulfones with sulfuryl chloride in which the most noteworthy observation was exclusive or highly selective β-chlorination of diethyl sulfone or sulfolane (tetrahydrothiophene-1,1-dioxide) is described. The most successful synthetic application of this method was exemplified by the chlorination of 7-thiabicyclo[2

  Cl原子的引入通常发生在烷基砜的α原子的α位。在本文中，描述了一种新的烷基砜与磺酰氯的离子氯化方法，其中最值得注意的观察是二乙基砜或环丁砜（四氢噻吩-1,1-二氧化物）的独家或高度选择性的β-氯化。这种方法的最成功的合成应用程序是通过例举7-硫杂二环[2.2.1]庚烷-7,7-二氧化物的氯化，这提供2-外-和2-内型-氯-7-硫杂二环[2.2.1 ]庚烷-7,7-二氧化物，这是可能是因为不希望的均裂SO的难以通过自由基氯化获得，2 C键裂变。2-外将如此获得的-氯-7-噻二环[2.2.1]庚烷-7，7-二氧化物选择性还原，得到2-外-氯-7-硫代双环[2.2.1]庚烷。还讨论了这种氯化的机理。

  作者：Christopher M. Poteat、Vincent N. G. Lindsay

  日期：——

  The direct and selective α-mono-bromination of alkyl sulfones was achieved through base-mediated electrophilic halogenation. The appropriate combination of solvent and electrophilic bromine source was found to be critical to control the nature of the products formed, where reagent–solvent halogen bonding is proposed to control the selectivity via alteration of the effective size of the electrophilic

  烷基砜的直接和选择性α-单溴化是通过碱介导的亲电子卤化作用实现的。发现溶剂和亲电子溴源的适当组合对于控制所形成产品的性质至关重要，在此，提出了通过改变亲电子溴源的有效尺寸来控制试剂-溶剂卤素键来控制选择性的方法。相反，多卤化后，在后处理过程中进行选择性脱卤后，以高收率选择性地获得了α，α-二溴代砜。两种方法都可以以克为单位进行应用，并且单卤化成功地扩展到烷基砜的全选择性α-氯化，α-碘化和α-氟化。
