Stepwise reactions of two N-CH2CN or two N-CH2C(NH)OMe groups attached to macrocyclic copper(II) complexes: Preparation of homo- and hetero-di-N-functionalized macrocyclic complexes

Various homo- and hetero-functionalized macrocyclic copper(II) complexes have been prepared selectively from a tetraaza macrocyclic copper(II) complex bearing two N-CH2CN pendant arms.
