Abstract
The present invention is directed to catalysts and processes for catalyzing two or more chemical reactions with a multifunctional catalyst in a reaction vessel. The processes include steps for introducing one or more reagents to a reaction vessel containing a multifunctional catalyst; contacting the one or more reagents with a first portion of the multifunctional catalyst to produce an intermediate; contacting the intermediate with a second portion of the multifunctional catalyst to produce a product; and removing the product from the reaction vessel. In certain embodiments, the multifunctional catalyst may have a first portion with carbonylation functionality for catalyzing the production of a beta-lactone intermediate from an epoxide reagent and a carbon monoxide reagent. In certain embodiments, the multifunctional catalyst may have a second portion with a functionality suitable for polymerization, co-polymerization, and/or modification of a beta-lactone intermediate. In preferred embodiments, the first portion and second portion are bonded to a heterogenous support.
