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.

Claim (Index 17):
A method, comprising contacting a compound of formula I with a neutral metal carbonyl compound to produce an aluminum-based carbonylation catalyst and a ketone, wherein:\n the compound of formula I is the neutral metal carbonyl compound is Q\u2032 d M e (CO) w\u2032 ; the aluminum-based carbonylation catalyst is \u2003and the ketone is wherein:\n Q is a nitrogen atom and the four Q groups are part of a single porphyrin ligand; \n R q  is selected from optionally substituted C 1-12  aliphatic and optionally substituted aryl; \n M is a metal atom; \n Q\u2032 is any ligand and need not be present; and, if present, is a phosphine ligand, a triaryl phosphine, a trialkyl phosphine, a phosphite ligand, an optionally substituted cyclopentadienyl ligand, cyclopentadienyl, or pentamethylcyclopentadienyl; \n d is an integer between 0 and 8 inclusive; \n e is an integer between 1 and 6 inclusive; \n w is a number such as to provide the stable anionic metal carbonyl complex; \n w\u2032 is a number such as to provide a stable neutral metal carbonyl complex; and \n y is the charge of the metal carbonyl anion.
