Toluene oxidation is one of the substantial industrial technologies since oxidized products are industrially very important intermediates. A Fe3O4@cysteine@Cu-catalysed reaction that uses tert-butyl hydroperoxide as oxidant to produce esters from toluene and β-diketones or β-keto esters, enolate precursors, has been developed. Oxidative esterification of toluene with 1,3-dicarbonyl derivatives led to C─O bond formation and direct C─H functionalization.

Superparamagnetic CuCl nanoparticles were prepared and identified as an effective heterogeneous catalyst for the tandem transformation of methylarenes and 1,3-dicarbonyl compounds into the corresponding enole esters by the use of tert-butyl hydroperoxide as an external oxidant. The catalyst can be removed from the reaction medium simply by use of an external magnet. As a consequence, various derivatives of enol esters were synthesized in moderate to good yields.
