Bridge the gap: Three air-stable binuclear sulfur-bridged organobismuth complexes have been synthesized and were found to show high cooperative catalytic effect on CO2 transformation into cyclic carbonates with epoxides (see scheme). By using a sulfur atom for bridging and varying the nitrogen substituent, one can regulate the ligand system of the bismuth centers to mimic those of the natural metalloenzymes.
