Abstract A decarbonylation free, polystyrene‐supported, Pd (Pd@PS)‐catalysed carbonylative esterification of the hydroxy group of 5‐hydroxymethyl furfural (5‐HMF) to its corresponding aryl esters has been developed. The use of Pd@PS, oxalic acid as CO source, and aryl halides was first explored for the aryl ester of 5‐HMF synthesis. Here, we investigated the vital role of a polystyrene support to avoid the commonly known decarbonylation of 5‐HMF. The reaction exhibits vast substrate scope with comparably good yield and catalyst recyclability.
