aldehydes or ketones in the presence of a borane-pyridine complex and acetic acid in benzene at 40 °C affords the corresponding N-alkyl- S, S-diphenylsulfimides. Since this reaction does not form the N,N-dialkylated aminosulfonium salt, this method provides a convenient preparation of N-monoalkylsulfimides without the necessity for a difficult separation of the products by column chromatography due to their
N-未取代的 S,S-二苯基亚磺酰亚胺与醛或酮在硼烷-吡啶络合物和乙酸的存在下在苯中于 40 °C 反应得到相应的 N-烷基-S,S-二苯基亚磺酰亚胺。由于该反应不形成 N,N-二烷基化氨基锍盐,因此该方法提供了一种方便的 N-单烷基亚磺酰亚胺制备方法,而无需由于其相似的 R f 值而通过柱色谱法难以分离产物。讨论了形成的机制。
