C-Alkyl-bis-phosphoryl chelating systems for the potential recovery of strategic metals
Résumé
Methylene-bis-phosphonic acid and derivatives are used as complexing agents, diagnostics, therapeutics and show interesting virustatic properties. We describe the syntheses of mono- and di-substituted bisphosphonates and mono- and disubstituted diethyl ((diphenylphosphoryl)methyl)phosphonate as possible chelating systems for the recovery of strategic metals.
