Electrochemical synthesis, structure, magnetic and tribochemical properties of metallochelates of new azomethine ligands, bis-[2-(N-tosylaminobenzylidenealkyl(aryl)]disulfides

The use of sacrificial anodes for the electrochemical synthesis of metallic complexes

“…A similar proligand, 2-(tosylamino)-N-[2-(tosylamino)benzylidene]aniline (H 2 L28), was electrolyzed with cobalt, nickel, copper, zinc and cadmium anodes in acetonitrile [91] or methanol [92] giving The electrochemical syntheses of metal complexes starting from tosylamido-Schiff bases which also include a disulfide moiety in acetonitrile have also been reported; that is the case of the proligands N,N-(dithiodialkyl(aryl)bis-(aminylydenemethylydene)-bis (1,2-phenylene) ditosylamides (HL6-L6H); alkyl = -(CH 2 ) 2 - [28,98], HL6a-L6Ha; aryl [99] = orthoPh-; HL6b-L6bH) and so the syntheses of Fe(II) [28], Co(II) [28], Ni(II) [28,99], Cu(II) [28,99], Zn(II) [98,99] and Cd(II) [98,99] complexes with the corresponding ligand were described. The molecular structures of [M(L6a-L6a)]·CH 3 CN (M(II) = Fe, Co, Ni, Cu and Zn) and [Cd(L6a-L6a)] complexes were confirmed by X-ray diffraction studies [28,98].…”
