A simple route to amide-functionalized tetravalent metal phosphonates. Interlayer amidation of an ethylenediammonium exchanged form of zirconium carboxyethylphosphonate
Abstract
A simple route to layered tetravalent metal phosphonates containing amide linkages is demonstrated by a model reaction in which the ethylenediammonium ion exchanged form of layered zirconium carboxyethyl-phosphonate is converted into the amide derivative by thermal condensation.
