Abstract/Summary Carbonyl insertion reactions have recently been shown to be excellent synthetic routes to important monomers that can act as starting materials for biodegradable polymers. The insertion reaction into epoxides to yield β-lactones and from β-lactones to succinic anhydrides are both catalyzed by Lewis Acid cation / cobalt carbonyl anion salts which depend on the Lewis Acid for activity. A series of different Lewis Acids with differing electronic properties were successfully synthesized using two different synthetic methods. A novel strapped ligand for the Lewis Acid was also synthesized that should alter the binding capacities of free solvent on the system.
