Abstract

The synthesis of cyclic ethers based on polyethyleneglycol chains grafted on di (o- hydroxyphenyl) amine is described. The starting diarylamine is obtained from a melted salt procedure and coupled to the tosylated tri-, tetra-and pentaethyleneglycol. The X-ray crystal structure of the tetraethyleneglycol derivative was determined. For the triethyleneglycol compound, alkylation of the nitrogen atom with 5-bromomethyl-5′-methyl-2, 2′- ...
