Nonfluorous, Highly CO_2-soluble Chelating Ligands for scCO_2 Metal Ion Extraction
A series of new nonfluorous chelating ligands derived from glucose have been designed and synthesized. All compounds are highly soluble in liquid or supercritical carbon dioxide. Solubility trend of these chelating compounds would be rationalized by the inductive effect of substituent on the benzene ring and the easy accessibility of benzylic ether oxygen and neighboring hydrogens. Preliminary metal ion extraction efficiency test showed that all our compounds are selective for Sr<SUP>2+</SUP> and Pb<SUP>2+</SUP> extraction.
