Background: Co(II) meso-Tetra (4-methoxyphenyl) porphine (1-3% chlorin) has been used as a selective potentiometric sensor for arsenite and molybdate in aqueous media^1,2. Electrochemical oxygen reduction reaction activity has been observed with this porphyrin^3,4. C-O Bond cleavage of alcohols via visible light activation of cobalt alkoxycarbonyls derived from Co(II) meso-tetra(4-Methoxyphenyl)porphine⁵. Co(II) porphyrins are highly efficient catalysts towards desulfurization of dibenzothiophene in fuel oils⁶. T(p-OMe)PPCo is an effective catalyst for the aerobic oxidative coupling of phenols⁷. Cobalt(II) porphyrins are effective catalysts for selective cyclopropanation of alkenes with ethyl diazoacetate⁸.
