In this issue, C. Hertweck et al. review terpenoid biosynthesis with unconventional cyclases. What is their impact on biomimetic synthesis? In a Correspondence, G. Frenking and G. F. Caramori argue that there is no need to re-examine the electrostatic notion of the hydrogen bonding. F. Weinhold and R. A. Klein reply that the general understanding of the hydrogen bond can be improved. In his Editorial, H. Hopf discusses the role of chemical societies and their members in Germany during the Nazi regime and World War II: the GDCh tasked an independent science historian with an analysis in 2007, which will be published as a book later this year.
In the Communications section, B. Klötzer et al. show how to enhance the electrochemical water-splitting kinetics of near-surface iron atoms (see picture). A. D. Hamilton et al. found β-strand mimetic foldamers to be rigidified through dipolar repulsion. W. Sander et al. succeeded in the isolation of the elusive fluorenyl cation, and S. Kawauchi et al. oberserved bond formation and coupling between germyl and bridging germylene ligands in dinuclear palladium complexes.
