A General Approach to Creating Soluble Catalytic Polymers Heterogenized in Microcapsules

A general method for preparing site-isolated polymeric catalysts is presented. Linear chloromethyl and azide polymers have been sequestered within polyurea microcapsules and small molecule catalysts soaked through the shell walls to functionalize the soluble polymers. Reaction onto each type of supp...

Summary:A general method for preparing site-isolated polymeric catalysts is presented. Linear chloromethyl and azide polymers have been sequestered within polyurea microcapsules and small molecule catalysts soaked through the shell walls to functionalize the soluble polymers. Reaction onto each type of support is quantitative and MacMillan, DMAP, and TEMPO test catalysts are shown to have faster reaction rates than the analogous resin-supported catalysts.
