Abstract

The invention is directed to a microcapsule containing a catalyst. The invention also provides a system for making and using these microcapsules. The inventive microcapsules may be hollow and, further, may encapsulate a solution. Moreover, the catalyst may be soluble in the encapsulated solution. The semi-permeable shell of the microcapsule allows reactants to diffuse into the interior of the microcapsule and react with the catalyst to form a product which may diffuse out of the microcapsule. Using such a system, one pot multi-step reactions can be conducted in the presence of incompatible catalysts, incompatible reagents, and/or incompatible microenvironments.
