Catalytic Activity of Iron and Ruthenium Complexes of Bis (2, 3-dihydroxy benzaldehyde) pyridine diimine towards Oxidation of Cyclohexene, Cyclohexane, THF and Alcohols Using O …
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.
