A referee highlighted a recent report on the 'Role of metal contaminants in catalyses with FeCl₃' (S. L. Buchwald and C. Bolm, Angew. Chem., Int. Ed. Engl., 2009, 48, 5586–5587). In order to investigate the influence of the impurities in the FeCl₃ on the reaction of sulfonyl azide with tertiary amine, the authors measured the contents of the metal impurities in the FeCl₃ that they used and several control experiments were carried out. The results are given in the electronic supplementary information.
