    • As previously observed (See: Ref. [17b]), the oxidation of chloride anion to chlorine occurs close to the second oxidation process associated with the TTF unit. As a consequence of the overlapping nature of these two oxidation processes, it is not possible to obtain any information as to whether complexation of chloride anions to compounds 1 or 2 also affects the second oxidation process associated with the TTF unit in these two compounds.
