A Materials Approach to the Dual-Site Isolation of Catalysts Bonded to Linear Polymers and Small, Ionic Molecules for Use in One-Pot Cascade Reactions
Site isolation of ionic catalysts and polymer-bound catalysts is achieved by placement on different sides of PDMS membranes. Ionic molecules and polymers do not flux through the PDMS membranes, but organic molecules can flux through the membranes and react with catalysts that are incompatible with each other. This is a general approach to site-isolate catalysts from each other.
