48. A referee has drawn our attention to the fact that the different populations of isomers S in complexes 1 and 2 could be related to the ligand trans to the allyl: pyrazole for 2, but Br for 1. In fact, there is a clear preference for the pyrazole against the bromo ligand in complexes 1, whereas a more balanced competition between acac and the pyrazole seems to take place in complexes 2.
