Abstract
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, such as the alkylaluminum complexes represented by Formula I, where Q is a nitrogen atom and the four Q groups are part of a single porphyrin ligand and Rq is selected from optionally substituted C1-12 aliphatic and optionally substituted aryl:
