Long chain n‐ Alkyl monoaza crown ethers

Abstract

Abstract Homogeneous polyoxyethylated long chain alkylamines with 5 to 7 oxyethylene units were prepared by the reaction between oligoethylene glycol monochlorides and alkylamines. They were converted to the corresponding long chain N‐alkyl monoaza crown ethers by treatment with p ‐toluene‐sulfonyl chlorides in the presence of alkali metal hydroxides in dioxane. The physical and spectral properties of these new derivatives of alkylamines were investigated in detail.
