The Co(II), Ni(II) and Cu(II) complexes with the shiff bases – derivatives of 8-aminochinoline and 5-brom-  and 3,5-di-tret-butilsalicylaldehyde, their reduced on azometine group analogues have been synthezed. By the metods of elemental analysis, IR- and UV-VIS spectrometry the structure of these compounds was investigated. It has been shown that both reduced schiff bases undergo easily the oxidative dehydrogenation in complex formation process
