Cooking with gas: Copper complexes serve as excellent catalysts for the directcarboxylation of aromatic heterocyclic CHbonds with CO2, thereby offering an economical and environmentally benign process for the synthesis of heterocyclic carboxylic esters (see scheme; IPr=1,3‐bis(2,6‐diisopropylphenyl)imidazol‐2‐ylidene). Some active intermediates of this reaction have been isolated and structurally
