Abstract: A PROCESS IS DISCLOSED FOR PREPARING TRIVALENT COBALT DERIVATIVES REPRESENTED BY THE FORMULA:

X-A-CO(-L1)(-L2)(-L3)-L4

WHEREIN L1, L2, L3 AND L4 MAY BELONG TO THE SAME LIGAND MOLECULE, E.G., A PLANAR TETRADENATE LIGAND SUCH AS BIS(DIACETYLMONOXIMEIMINO)-PROPANE, OR TO TWO MOLECULES OF A BIDENATE LIGAND SUCH AS O-PHENANTROLINE, OR MAY BE FOUR MONODENTATE LIGANDS; A IS A DIVALENT RADICAL SUCH AS -CH2-; X IS A FUNCTIONAL GROUP SUCH AS -NO2: BY CAUSING THE CORRESPONDING DIVALENT COBALT COMPLEXES TO REACT WITH MOLECULAR OXYGEN IN THE PRESENCE OF AN ALCOHOL SUCH AS METHANOL, AND A NEW TRIVALENT COBALT COMPOUND IS PRODUCED WHICH IS THEN ALLOWED TO REACT WITH A COMPOUND HAVING THE FORMULA HA-X WHEREIN A AND X HAVE THE MEANING SET FORTH ABOVE.

Abstract: A PROCESS IS DISCLOSED FOR PREPARING TRIVALENT COBALT DERIVATIVES OF THE FORMULA

1-((-)O-),2-((2-((-)O-)PHENYL)-CH=N-CH2-CH2-N=CH-)BENZENE

X-CH2-(-) CO(+3)

WHEREIN X IS NO2, CN. CH3CO OR CHO WHICH COMPRISES REACTING A SUSPENSION OR SOLUTION CONTAINING A DIVALENT COBALT COMPLEX OF THE FORMULA IG-02 METHANOL AND A REACTANT OF THE FORMULA CH3-X WHEREIN, X AS AS DEFINED ABOVE, AT A TEMPERATURE FROM 0*C. TO 80*C. WHILE SIMULTANEOUSLY INTRODUCING OXYGEN GAS INTO SAID SUSPENSION OR SOLUTION.
