Dipinodiazafluorenes as Reagents for the Selective Extraction of Palladium, Gold, and Ruthenium

Dipinodiazafluorenes are hybrid nopinane-annelated heterocycles whose molecules include a heterocyclic core of 4,5-diazafluorene fused with fragments of terpene hydrocarbon; they can selectively extract palladium (88−100%), gold (42−96%), and ruthenium (8−19%) by single extraction from acidic aqueou...

Zusammenfassung:Dipinodiazafluorenes are hybrid nopinane-annelated heterocycles whose molecules include a heterocyclic core of 4,5-diazafluorene fused with fragments of terpene hydrocarbon; they can selectively extract palladium (88−100%), gold (42−96%), and ruthenium (8−19%) by single extraction from acidic aqueous solutions (pH 1.2) containing complex mixtures of 3 d elements and noble metals.
