Abstract
The synthesis of (hydroxymethyl)-18-crown-6 and of (hydroxymethyl)[2.2. 2] cryptand is described. These systems allow facile binding of lipophilic chains and/or of polymeric matrices. In this way efficient chemically stable phase-transfer catalysts are obtained. Polymer-bound systems are easily recyclable without loss of catalytic activity. Use of these systems for the removal of lanthanide shift reagents from organic solutions is reported.
