In this study, magnetic reduced graphene oxide supported CuO was demonstrated as a heterogeneous catalyst for the synthesis of esters in cross dehydrogenative coupling reactions. Various benzylic esters were efficiently prepared using methyl aromatics and aldehydes/benzyl alcohols as coupling partners, with tert-butyl hydroperoxide as a green oxidant and tetra-n-butylammonium bromide/tetra-n-butylammonium iodide as additives. The catalyst could be easily separated through simple filtration due to its heterogeneous nature.
Magnetic reduced graphene oxide supported CuO (rGO/Fe3O4-CuO) as a heterogeneous catalyst in cross dehydrogenative coupling (CDC) reactions has been demonstrated for the synthesis of esters using methyl aromatics and aldehydes/benzyl alcohols as coupling partners. Various benzylic esters were prepared efficiently from cheap raw chemicals by employing tert-butyl hydroperoxide (TBHP) as a green oxidant and tetra-n-butylammonium bromide (TBAB)/tetra-n-butylammonium iodide (TBAI) as additives. Because of the heterogeneous nature of this catalytic system, simple filtration was used to separate the catalyst.
