  一锅合成亚砜，利用DABSO /三甲基甲硅烷基氯序列产生的亚磺酰二阳离子当量

  摘要：

  描述了一种使用有机金属亲核试剂合成不对称亚砜的一锅法。从替代DABSO（DABCO- bis（二氧化硫））输送的二氧化硫用作初始亲电试剂，并与第一种有机金属试剂结合生成亚磺酸盐中间体。使用TMS-Cl（三甲基甲硅烷基氯）将亚磺酸盐原位转化为亚磺酸盐甲硅烷基酯可生成第二亲电试剂，从而可添加第二有机金属试剂。可以使用有机锂或格氏试剂，以高至极好的收率递送亚砜。

  A transition-metal-free arylation of sulfenate anions generated from β-sulfinyl esters with diaryliodonium salts was developed. In this process, a new C–S bond is formed under mild reaction conditions providing a wide range of S,S-diaryl and S-alkyl S-aryl sulfoxides.

• Reaction of simple arenes with FSO3H.cntdot.SbF5/SO2: one-pot synthesis of aromatic sulfoxides. Mechanistic aspects and synthetic utility

  日期：1991.3

  In a simple one-pot reaction, mono-, di-, tri-, and polyalkylbenzenes, isomeric alkylhalobenzenes, and fluoro-, (trifluoromethyl)-, and 1,3,5-trifluorobenzene were converted to their corresponding diaryl sulfoxides with FSO3H.SbF5 (1:1) (magic acid)/SO2. Dependency of the yields on the acidity (H0) and the arene structure was demonstrated. Reduction of the formed sulfoxide was also observed as a minor pathway to give diaryl sulfide. The reduction is superacid-catalyzed, and protonated sulfoxides are the key intermediates en route to sulfides. Protonation of several functionalized diaryl sulfoxides was also studied in magic acid/SO2 under stable ion conditions. Unlike the parent diphenyl sulfoxide, which is S-protonated, alkyl-, fluoro-, and trifluoromethyl-substituted diaryl sulfoxides O-protonate to give long-lived sulfoxonium ions. The proposed mechanism for the arene/superacid/SO2 system involves sulfination of the arenium ions, O-protonation of the resulting sulfinic acid, dehydration of the oxonium ion ''ArSO+'' and arylation. In the absence of SO2, the fluorosulfonation, ionization, arylation path becomes dominant. The scope of the reaction is sufficiently broad to be synthetically useful. The methodology is also applicable to unsymmetrical (mixed) diaryl sulfoxides.
