Abstract

The oxidation of primary alcohols, cyclohexene, cyclohexane and tetrahydrofuran (THF) was studied using the catalysts [Fe(L)ClH2O] (1) and [Ru(LH2)PPh3Cl2H2O] (2) where L = bis(2,3-dihydroxy benzaldehyde)pyridine diimine in various solvents and co-oxidants. Primary aromatic alcohols gave better yields compared to aliphatic alcohols. Both catalysts oxidized cyclohexene into cyclohexene-1-ol and cyclohexene-1-one in almost 1:1 ratio with negligible epoxide formation. The conversion of cyclohexane into cyclohexanol and cyclohexanone was most effective with t-BuOOH as co-oxidant. For THF, iron complex 1 gave better results than ruthenium complex 2.
