A SIMPLE ROUTE TO AMIDE-FUNCTIONALIZED TETRAVALENT METAL PHOSPHONATES- INTERLAYER AMIDATION OF AN ETHYLENEDIAMMONIUM EXCHANGED FORM OF ZIRCONIUM CARBOXYETHYLPHOSPHONATE
T. Kijima et al., A SIMPLE ROUTE TO AMIDE-FUNCTIONALIZED TETRAVALENT METAL PHOSPHONATES- INTERLAYER AMIDATION OF AN ETHYLENEDIAMMONIUM EXCHANGED FORM OF ZIRCONIUM CARBOXYETHYLPHOSPHONATE, Journal of the Chemical Society. Dalton transactions, (24), 1993, pp. 3827-3828
A simple route to layered tetravalent metal phosphonates containing am
ide linkages is demonstrated by a model reaction in which the ethylene
diammonium ion exchanged form of layered zirconium carboxyethyl-phosph
onate is converted into the amide derivative by thermal condensation.
