SYNTHESIS OF HETERO-POLYTOPIC CRYPTANDS INCORPORATING HARD AND SOFT DONOR ATOMS VIA TRIPOD-TRIPOD SCHIFF BASE CONDENSATION - VERSATILE LIGANDS FOR TRANSITION METAL IONS

摘要

Template synthesis of four new cryptands has been described. In each of these cryptands. there are three distinct compartments. These cryptands readily make mono- as well as binuclear cryptates with transition metal ions like copper. nickel etc. The dicopper cryptates reduce in solution to the Cu(I) state. [References: 15]
