Summary

The Mn(Salen)Cl and Ni(Salen)-catalyzed oxidation of limonene has been carried out. The catalytic cycle involved PhIO <Emphasis Type=”Italic”>via</Emphasis> a rebound mechanism. In all cases the use of organic solvents resulted in reasonable selectivities of oxidized products. The use of supercritical carbon dioxide (SCCO<Subscript>2</Subscript>) led at least to comparable results in terms of conversions, but showed different selectivities. In ordinary solvents epoxidation appears to predominate over allylic oxidation. This tendency, in SCCO<Subscript>2</Subscript>, appears only after 4 h of reaction. Shorter reaction times (2 h) appear to lead to opposite selectivity. These results showed the advantages of using SCCO<Subscript>2 </Subscript>as solvent in these reactions. SCCO<Subscript>2</Subscript> is much more compatible with green technology than are organic solvents.
