    摘要： The present disclosure provides novel methods of making aluminum complexes with utility for promoting epoxide carbonylation reactions. Methods include reacting neutral metal carbonyl compounds with alkylaluminum complexes. For example, a compound of formula I: is reacted with a neutral metal carbonyl compound (such as Q′dMe(CO)w′) to produce an aluminum-based carbonylation catalyst:

    摘要： A method of making acid anhydrides from epoxide and carbon monoxide feedstocks is presented. In various aspects, the method includes steps of reacting the contents of a feed stream comprising an epoxide, a solvent, a carbonylation catalyst and carbon monoxide to produce a first carbonylation product stream comprising a beta-lactone, then reacting the contents of the first carbonylation product stream with additional carbon monoxide to produce a second carbonylation product stream comprising an acid anhydride, and separating at least a portion of the acid anhydride from the second carbonylation product stream to produce: i) an acid anhydride product stream comprising the separated portion of acid anhydride; and ii) a recycling stream comprising the carbonylation catalyst, and finally adding the recycling stream to the feed stream.

    摘要： The present application provides a method for producing an beta-lactone product. The method includes the steps of: reacting an epoxide, a solvent with a carbonylation catalyst and carbon monoxide to produce a reaction stream comprising a beta-lactone then separating a portion of the beta-lactone in the reaction stream from the solvent and carbonylation catalyst to produce: i) a beta-lactone stream with the beta-lactone, and ii) a catalyst recycling stream including the carbonylation catalyst and the high boiling solvent; and adding the catalyst recycling stream to the feed stream.
