The reaction of an N-unsubstituted S,S-diphenylsulfimide1 with 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 similar Rf values. The mechanism of formation is discussed. Georg Thieme Verlag Stuttgart.
