The direct electrochemical synthesis of Ti(II), Fe(II), Cd(II), Sn(II), and Pb(II) complexes with N, N'-bis(salicylidene)-o-phenylenediamine

The electrochemical oxidation of anodic Ti, Fe, Cd, Sn, and Pb (=M) into acetonitrile solutions of N,N'-bis(salicylidene)-o-phenylenediamine $[SalophH_2]$ gives the corresponding M(Saloph) complexes in high yield. The mechanism of the electrochemical reactions is discussed. $SalophH_2$ forms complexes (1:1 molar ratio) with titanium, iron, cadmium, tin, and lead ions. The complexes have been characterized by elemental analyses, molar conductivity measurements, and infrared and electronic spectral data. The $SalophH_2$ complexes of iron(II) and cadmium(II) have been further identified by $^1H$-NMR and mass spectra.
