The successfully developed polydimethylsiloxane (PDMS, a stable hydrophobic polymer material) sponge supported DMAP can be used as base catalyst and ligand to facilitate a series of organic transformations with high efficiency and good reusability in water. This PDMS sponge DMAP can provide much better catalytic activities and selectivities than free DMAP in water. Through an easy-to-build continuous flow reactor, the PDMS sponge DMAP facilitated reactions can be facilely scaled up. This porous hydrophobic PDMS sponge material will be a promising carrier for the development of highly efficient recyclable catalysts in water. (C) 2018 Elsevier Inc. All rights reserved.
