| Abstract: |
Alumina-supported Mn(II) complexes with ligands of acetylacetonato (acac), N,N′-ethylenebis(salicylideneiminato) (salen), ethylenediamine (en) and 2,2′-bipyridine (bpy) catalyze the oxidation of cyclohexene with tert-butylhydroperoxide (TBHP) and hydrogen peroxide. Oxidation of cyclohexene with TBHP gave 2-cyclohexene-1-ol, 2-cyclohexene-1-one and 1-(tert-butylperoxy)-2-cyclohexene whereas, oxidation with H2O2 resulted in the formation of cyclohexeneoxide and cyclohexene-1,2-diol. Mn(II) catalysts with the nitrogen donor ligands show significantly higher catalytic activity than oxygen donor ligands at the same surface coverage. The mechanism of oxidation has also been discussed. [Copyright &y& Elsevier] |
