A number of β-phenyl(or benzyl)selanyl- and β-phenylsulfanyl- substituted imines possessing an additional donor nitrogen, oxygen, or sulfur atom were synthesized by reaction of 2-phenylsulfanylethanamine, 2-phenylsulfanylcyclohexanamine, 2-phenylselanylcyclohexanamine, and 2-benzylselanylaniline with salicylaldehyde, 2-pyridinecarbaldehyde, or 2-tert-butylsulfanylbenzaldehyde. The resulting Schiff bases were tested as ligands in the complex formation with nickel(II) and copper(II), and mononuclear (L-H)MCl or LMCl2 coordination compounds were isolated (L = sulfur- or selenium-containing imine). The redox properties of the selenium-containing ligands and complexes were studied by cyclic voltammetry. The complexes were found to undergo reduction of the metal ion in two one-electron steps. The reduction is reversible for copper complexes and irreversible for nickel complexes.
