Unsupported catalyst for green chemistry : The aerobic oxidation and coupling of primary alcohols (methanol, ethanol, n ‐butanol) to give the corresponding aldehydes and esters at temperatures below 100 °C is facilitated by unsupported nanoporous gold catalysts. The experimental conditions employed allow a close comparison to model experiments and open the door to a molecular‐level understanding of the reaction.
