Descripción

General description

Tetraisopropyl methylenediphosphonate (IPCP) is a tetraisopropyl ester of methylenediphosphonic acid. It is an electroneutral ligand, reported to be synthesized from triisopropyl phosphate. Powder electron paramagnetic resonance (EPR) studies of tris complexes of Cu(II) complexes with IPCP has been analyzed.

Application

Tetraisopropyl methylenediphosphonate [T(iPr)MDP] forms a synergistic mixture with hydrogen dicarbollylcobaltate in nitrobenzene which was used in the extraction of europium and americium.
It may be used in the synthesis of the following:

• tetraisopropyl ethenylidenebisphosphonate.
• tetraisopropyl 4-acetylthiobutane-1,1-diphosphonate
• tetraisopropyl 2-(3,5-bis(bromomethyl)phenyl)ethane-1,1-diphosphonate
