Designer ligands. VIII. thermal and microwave-assisted synthesis of silver(I)-selective ligands

摘要

Thermal and microwave-assisted methods have been used for preparing multidentate malonamide derivatives as silver(I)-selective ligands, the latter methodology providing convenient and rapid access to the target compounds in yields of up to 92%. Metal extraction studies revealed that some of the ligands exhibit selectivity for silver (over the base metals, copper and lead), ranging from moderate to excellent.
