Improved access to polythioesters by heterobimetallic aluminium catalysis

Bimetallic Al( iii ) catalysis mediates thioanhydride/epoxide copolymerisation at greatly improved rates and monomer tolerance than analogous Cr( iii ) catalysis. Moving to sulfurated monomers furthermore generally improves rates and selectivites. Heterobimetallic Aluminium catalysis gives fast acce...

Description
Summary:Bimetallic Al( iii ) catalysis mediates thioanhydride/epoxide copolymerisation at greatly improved rates and monomer tolerance than analogous Cr( iii ) catalysis. Moving to sulfurated monomers furthermore generally improves rates and selectivites. Heterobimetallic Aluminium catalysis gives fast access to polythioesters from thioanhydride ring-opening copolymerisation and reveals general trends on the effects of monomer sulfuration.
