  tested for AT1 receptor antagonist properties. While the sulfur-containing systems were prepared following existing methodology, the selenium-containing analogues required the development of novel, tandem free-radical chemistry involving addition of aryl radicals to alkynes, followed by intramolecular homolytic substitution at the higher heteroatom. All four compounds prepared proved to be excellent

  Selenocephems (14 and 15) and selenopenams (18, 20, 24 and 25) can be prepared in 18-85% yields through the intramolecular homolytic substitution of aryl or alkyl radicals at the selenium atom in suitably-substituted 4-benzylseleno-beta -lacrams, ol through intramolecular nucleophilic substitution by the benzylseleno moiety in 4-halo-beta -lactam precursors.

  A number of beta-phenyl(or benzyl)selanyl- and beta-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. DOI: 10.1134/S1070363213020138
