47_02/2008Cover Picture: A Supramolecular Catalyst for Regioselective Hydroformylation of Unsaturated Carboxylic Acids (Angew. Chem. Int. Ed. 2/2008)

The Venus Flytrap ... ...waits patiently for unsuspecting prey. Once it recognizes an insect in the trap, the jaws close and soon the plant digests its meal. In their Communication on page 311 ff., T. Šmejkal and B. Breit describe the development of a novel catalytic system which combines supramolecular recognition of the substrate and transition-metal catalysis. This catalyst can effect challenging transformations such as the regioselective hydroformylation of an internal alkene.

Hydrogen Activationfor001

The ever-increasing global demands for energy have led to renewed interest in the chemistry of hydrogen. R. D. Adams and B. Captain summarize recent studies on unsaturated mixed-metal cluster complexes for the activation of hydrogen in their Minireview on page 252 ff.

Asymmetric Allylationsfor002

The Review by S. Ma and Z. Lu on page 258 ff. illustrates the substrate scope for metal-catalyzed asymmetric allylic alkylations. In practice, most catalytic systems are metal complexes of Pd, Mo, Ir, or Cu with chiral phosphorus ligands.

Actinide Clustersfor003

Plutonium(IV) in aqueous solutions often forms ill-defined precipitates. As described in the Communication on page 298 ff., L. Soderholm, P. C. Burns, et al. were able to characterize monodisperse PuO2-based nanoparticles formed in such solutions.
