A safe, facile and low‐leaching (up to 0.04 ppm) method has been developed for the removal of allyl, prenyl and benzyl protecting groups from the corresponding esters, using a sulfur‐modified gold‐supported palladium (SAPd) nanoparticle catalyst, which is known to be non‐flammable. The catalyst itself was found to be recyclable and the reaction appeared to proceed on the surface of the SAPd.
