AbstractPolydimethylsiloxane (PDMS, a stable hydrophobic polymer material) sponge‐supported nanometer‐sized gold can be used as a highly efficient recyclable catalyst for cross‐dehydrogenative coupling of tertiary amines with various nucleophiles in water. This PDMS sponge nanometer gold catalyst can provide much better activity than the free nanometer gold in water. The reaction can be scaled up by using an easy‐to‐build continuous flow reactor. These results indicate the potential application of porous hydrophobic PDMS sponge material as a promising support for highly efficient recyclable catalysts in water.
