PhS(O)(CH2)nCH2OH(n = 1–3) react with sulfuryl chloride at −78° or 0° in methylene chloride to give the corresponding PhSO2(CH2)nCH2Cl. Evidence is presented that cyclic alkoxyoxosulfonium salts are intermediates in these transformations. When n = 4 only chlorination α to the sulfoxide function was observed. The sulfinyl carboxylic acids PhS(O)(CH2)nCO2H (n = 1–3) and amides PhS(O)(CH2)nCONH2 (n = 1–3) were also reacted with SO2Cl2. α-Chlorination was observed for both compounds when n = 1 or 3. When n = 2 the products were the 3-phenylsulfonylpropionyl chloride and 3-phenyl-sulfonylpropionitrile respectively.
PhS(O)(CH₂)ₙCH₂OH(n = 1–3) 在氯化亚砜氯在−78°或0°的氯化亚砜中反应,得到相应的PhSO₂(CH₂)ₙCH₂Cl。有证据表明,环状烷氧氧代磺鎓盐是这些转化中间体。当n = 4时,只观察到对亚砜功能的α氯化。烷磺酰基羧酸PhS(O)(CH₂)ₙCO₂H (n = 1–3) 和酰胺PhS(O)(CH₂)ₙCONH₂ (n = 1–3) 也与SO₂Cl₂反应。当n = 1或3时,两种化合物均观察到α氯化。当n = 2时,产物分别为3-苯基磺酰基丙酰氯和3-苯基磺酰基丙腈。
