Lifting the curtain on metal-free hydrogen activation and hydrogenation: The successive splitting of molecular hydrogen under mild conditions by “frustrated Lewis pairs” based on inexpensive, stable amines in combination with B(C6F5)3 is presented by B. Rieger, T. Repo et al. in their Communication on page 6001 ff. The successful reduction of benzaldehyde is encouraging for the development of amine-B(C6F5)3 systems for the catalytic hydrogenation of olefins, carbonyl functions, and imines.

Polyunsaturated fatty acids form cyclic metabolites in vivo through autoxidative radical reactions. U. Jahn, J.-M. Galano, and T. Durand summarize in their Review on page 5894 ff. the structures, formation, biological activities, applications, and synthesis of these fatty acids.


The discovery of giant magnetoresistance laid the foundation for spintronics, whose applications have revolutionized areas such as hard-disk technology. The discovery of this area is described by A. Fert in the Nobel lecture on page 5956 ff.


Bases can be made photoswitchable as described in the Communication by S. Hecht et al. on page 5968 ff. The approach enables control over the activity of a general base catalyst by light.
