概要

• 論文の詳細を見る

• Monoaza crown ethers were prepared in satisfactory yields by the one-step reaction between diethanolamine or <I>N</I>,<I>N</I>-di[oligo(oxyethylene)]amines and oligoethylene glycol di(<I>p</I>-toluenesulfonates) or corresponding dichlorides in <I>t</I>-butyl alcohol/dioxane in the presence of sodium or potassium <I>t</I>-butoxide. The reaction conditions in the preparation of monoaza 15- and 18-crown ethers were studied. Various monoaza crown ethers having substituents were also prepared and their properties were investigated.
