Manganese-corrole complexes as versatile catalysts for the ring-opening homo- and co-polymerization of epoxide.

Manganese-corrole complexes in combination with a co-catalyst [PPN]X ([PPN](+)=bis(triphenylphosphoranylidene)iminium) were found to be new versatile catalysts for the polymerization of epoxides, copolymerization of epoxides with CO2, and copolymerization of epoxides with cyclic anhydrides affording a wide range of polymeric materials. This work should allow the synthesis of new types of improved innovative (co)polymers with original properties and would clearly increase the number of applications for polyesters, polycarbonates, and polyethers.
