Novel Mn(III)chlorins as versatile catalysts for oxyfunctionalisation of hydrocarbons under homogeneous conditions

Novel Mn(III)chlorins have been obtained and used as efficient and versatile catalysts for oxyfunctionalisation of the cyclohexane with PhIO and H2O2. Mn(III)chlorin/H2O2 should be oxidising the alkane by a concerted mechanism, whereas in Mn(III)chlorin/PhIO oxidations a free alkyl mechanism is operating, similarly to that observed in the oxidations catalysed by fluorinated Mn(III)porphyrins.
