The temperature‐dependent transformation of a ligand used for the selective trimerization of ethene has been investigated. In their Full Paper on page 12127 ff. , U. Rosenthal, W. Müller et al. describe the coordination, deprotonation, rearrangement, and cleavage of the ligand backbone in the presence of trialkylaluminum compounds. The resulting complexes were characterized and tested in ethene oligomerization reactions and the results underline the remarkable importance of the ligand's structure for selectivity in these reactions.
