Results of thermodynamic and kinetic studies so far reported are summarized on the complex formation of saturated macrocyclic tri- (9 membered), tetra- (1215 membered), and penta- (1517 membered) amines with several matal ions such as Cu, Zn, Cd, Hg, and Pb. Together attached are data for closely related linear polyamine reactions. Comparisons are made between macrocyclic and linear systems, between macrocycles with different ring size, and between different metal ions, in order to discuss the effects of ligand cyclization, macrocycle ring size, and change in metal ions on the equilibria and kinetics of the complex formations. Some of the conclusions and postulates reached from the macrocyclic polyamine studies seem relevant to other macrocyclic systems including “crown ethers”.
