The substitution of the dialkylamine residue of N-(dialkylaminomethyl) amides with nucleophiles leading to the formation of the amidomethyl compounds, reported in several papers by Hellmann, et al. has been shown not to occur with sulfides and cyanide under the condition of heating in methanol preferably in the presence of sodium hydroxide, whereas the substitution of the amide residue is chiefly effected. By similar manners the substitution reactions of N-(α-dialkylaminobenzyl) amides with sulfides and cyanide have been also realized.

Aminoalkylation of alcohols and of thiols by N-[1-(benzotriazol-1-yl)alkyl]amines under mild conditions give N-(α-alkoxyalkyl)amines 2 and N-[α-(alkylthio)alkyl]amines 3, respectively, in good yields.

presence of sulfur–carbon bonds is transversal to several areas of chemistry, e.g., drug discovery, materials, and chemical biology. However, a lack of efficient and sustainable procedures for the preparation of thioaminals, the N,S-analogues of O,O-acetals, contributes to this functional group often being overlooked by the scientific community. In this work is described the formation of thioaminals in
硫碳键的存在涉及化学的多个领域,例如药物发现、材料和化学生物学。然而,硫胺醛(O,O-缩醛的 N,S-类似物)的制备缺乏有效且可持续的程序,导致这一官能团经常被科学界忽视。这项工作描述了三氟甲磺酸铜 (II) 促进水中硫胺醛的形成。
