Abstract

The reaction of N, N-di (oligooxyethylene) amines with arenesulfonyl chloride in the presence of alkali metal hydroxide was investigate. It was found that the monoarenesulfonates of N, N-di (oligooxyethylene) amines were first formed as intermediates, and their subsequent intramolecular cyclization gave N-unsubstituted monoaza crown ethers rather selectively.
