A series of cyclic and acyclic diamido-bis-sulfide ligands were synthesized by N-acylation of 1,2-bis(2-aminophenylthio)ethane and 1,4-bis(2-aminophenylthio)butane with acetic, malonic, and 3,3′-dithiodipropionic acid chlorides or esters. The complexation of obtained ligands with CuII, NiII, and CoII salts in solution and on the gold electrode surface was studied. The formation of complexes of these ligands with copper(II) chloride in DMF is irreversible and accompanied by deprotonation of the amide nitrogen atoms.
