In this issue, S.-Y. Liu et al. discuss the chemistry of azaborines in a Review. What progress was made since the first synthesis of a monocyclic 1,2-azaborine by Dewar 50 years ago? In a Minireview, Y. Yu et al. summarize achievements in the asymmetric transition-metal-catalyzed hydrogenation of N-unprotected nitrogen compounds by Brønsted acid activation strategies. The Highlight deals with superhydrophic porous metal–organic frameworks (C. Serre). In an Essay, H. Werner looks back at the turbulent history of sandwich complexes.
In the Communications section, M. B. Nielsen et al. present a tetrathiofulvalene-functionalized radiaannulene with multiple redox states. W. E. Buhro et al. succeeded in the synthesis of magic-sized CdSe nanoclusters. D. G. Hall et al. show how carbocycles can be formed by direct activation of alcohols with a boronic acid, and H. Hillebrecht et al. report on the first borosulfate (see picture).
