Abstract

The cooperative catalytic activity of several metal corrole complexes in combination with tetrabutyl-ammonium bromide (TBAB) has been investigated for the reaction of epoxides with CO₂ leading to cyclic carbonates. It was found that the use of just 0.05 mol % of a manganese(III)corrole with 2 mol % TBAB exhibits excellent catalytic activity under an atmosphere of CO₂ .

Keywords: carbon dioxide fixation; cooperative catalysis; corroles; quaternary ammonium salts; sustainable chemistry.
