What is Metal Complexes with Macrocyclic Ligands. XIV. Formation, dissociation and metal exchange with an N~2~S~2~‐macrocycle about?
## Abstract 10, 10, 12‐Trimethyl‐3,4‐benzo‐1,6‐dithia‐9,13‐diazacyclopentadecen‐dihydrochloride (LH, **2**) and its Ni^2+^ complex were synthesized and their reactivity studied. The formation kinetics of **2** with Cu^2+^ were found to be a second order reaction between Cu^2+^ or CuACO^+^ and the monoprotonated form of the ligand LH^+^. The rate constant __k__ = 29 M^−1^S^−1^ is 10^5^–10^6^ times smaller than those of monoprotonated tetraazamacrocycles either because of second bond formation or because of a strong electrostatic interaction between the positive charges of the Cu^2+^ and the ammonium group. The metal‐metal exchange between NiL^+^ and Cu^2+^ was also investigated. The reaction is independent of [Cu^2+^] and has the same rate and activation parameters as the dissociation of NiL^2+^. In contrast to open chain ligands, no mixed complex CuNiL^4+^ as intermediate was observed.
