Résumé
The new multifunctional ligand thiophene-2,5-bis(carboxylatomethylenebenzotriazole) (<b>1</b>) reacts with [RhCl(CO)<sub>2</sub>]<sub>2</sub> to give the rhodium complex [RhCl(CO)(<b>1</b>)]<sub>2</sub> (<b>2</b>), which was found to catalyse efficiently the iodide-mediated carbonylation of methanol. The macrocyclic carbonyliodorhodium complex [Rh<sub>2</sub>I<sub>6</sub>(CO)<sub>2</sub>(<b>1</b>)]<sub>2</sub> (<b>3</b>) was isolated from the catalytic mixture and structurally characterised.
