K. Matsumoto et al., SYNTHESIS OF NEW ARMED CYCLOPOLYAMINES AND THEIR SELECTIVE EXTRACTIONPROPERTIES FOR METAL-IONS, Heterocycles, 41(2), 1995, pp. 237-244
A variety of new armed cyclopolyamines were prepared by high pressure
SNAr reactions (0.8 GPa, 100 degrees C) of cyclopolyamines with hetero
aromatic halides. Certain of these agents show selective extraction pr
operties for Hg2+ and Ag+ ions.
