The co-operative effect in the activation of the phenoxide anion with oligo(oxyethylenes) containing quaternary ammonium groups
Abstract
An unusual increase in activity accompanying the catalysis of a model substitution reaction between sodium phenoxide and 1-bromo-octane with oligo(oxyethylenes), linear or bound to the polymer, was observed after the introduction of quaternary ammonium groups as terminal groups into the oligo(oxyethylene) chain.
