Arylboronic acid and DMAPO cooperatively catalyse the dehydrative condensation reaction between carboxylic acids and amines to give the corresponding amides under azeotropic reflux conditions. This cooperative use is much more effective than their individual use as catalysts.

China From Above (27 photos)

A collection of recent aerial images showing the vast diversity of landscapes across China, from cities to mountains, desert to sea shores, and much more.
Aerial view of an abandoned Chinese fishing village overtaken by green vines on Shengshan Island, one of hundreds that make up Shengsi Islands, in east China's Zhejiang Province, on June 12, 2015. Vines climb the old stone walls, weave through the windows and doors, and creep along the crumpling paths in the village which has been reclaimed by Mother Nature.

[Perspective] Expanding the chemical space for redox flow batteries

by Mike L. Perry
Redox flow batteries (RFBs) have many advantages for grid-level energy storage, a key requirement for implementing intermittent renewable sources. Like other rechargeable batteries, a flow battery uses reversible electrochemical couples on two electrodes to store chemical energy (1). However, instead of storing the active materials within the electrodes, the reactants are dissolved in two electrolyte solutions and stored in external tanks (see the figure). This configuration allows their cost to scale better as size increases compared to conventional batteries. To date, the redox-active species have often been transition-metal ions, which can have limited electrochemical potential range. On page 1529 of this issue, Lin et al. (2) report on the use of transition-metal complexes and organic molecules as redox species that are both low in cost and relatively nontoxic. Author: Mike L. Perry

Dyotropic rearrangement..something I don't hear every day.

  • Michael F. Croisant, Ryan Van Hoveln, Jennifer M. SchomakerFormal Dyotropic Rearrangements in Organometallic Transformations Organometallic dyotropic rearrangements involve interchange of two groups on a stationary scaffold by breaking and reforming of two σ bonds. They proceed through various different mechanisms and yield a diverse array of products. This microreview traces recent developments and applications of formal dyotropic rearrangements involving both stoichiometric and catalytic amounts of transition metals. [Microreview]

Angewandte Chemie 38/2015: Volatility and Confinement

In this issue, H. Haick et al. review hybrid volatolomics and disease detection. How can volatile organic compounds be identified in biological cells? In a Minireview, E. Balaraman et al. discuss catalyzed hydrogen-transfer annulations as a means to access heterocyclic scaffolds. The Highlight deals with host materials for sulfur cathodes (H.-J. Peng and Q. Zhang). M. Daub and H. Hillebrecht contribute a Correspondence article on the structure of perovskite phases, and A. K. H. Hirsch summarizes the symposium that was recently held to commemorate the achievements of Nobel Laureate J.-M. Lehn's group

In the Communications section, A. Katz et al. show how weak-acid sites catalyze the hydrolysis of crystalline cellulose to glucose (see picture). E. P. Balskus et al. succeeded in the biosynthesis-assisted structure elucidation of chlorinated glycolipids from cyanobacteria. J. Mack et al. found an inexpensive and recyclable catalyst for the cyclopropanation of alkenes, and W. Schnick et al. obtained rare-earth-metal nitridophosphates through high-pressure metathesis.
