Cyclic hypervalent bromines act as aryne precursors

Diaryl λ3-bromanes are a rare and generally unresearched class of compounds. A mild and efficient protocol now delivers a broad palette of these interesting building blocks for organic synthesis. As a French research team ...

Stabilization of the borafluorene anion with carbenes

The incorporation of boron into polycyclic aromatic hydrocarbon systems leads to interesting chromophoric and fluorescing materials for optoelectronics, including organic light-emitting diodes (OLEDS) and field-effect transistors, ...

Found in space: Complex carbon-based molecules

Much of the carbon in space is believed to exist in the form of large molecules called polycyclic aromatic hydrocarbons (PAHs). Since the 1980s, circumstantial evidence has indicated that these molecules are abundant in space, ...

Global database for water-use efficiency

By examining the carbon isotope composition of tree-rings, researchers from Swinburne and the University of California, Davis have compiled the first comprehensive global database for water-use efficiency.

Stony corals: At the limits of adaption?

Corals fascinate amateurs and experts alike: small polyps that extract calcium carbonate from seawater and use it to build their elaborate skeletons. But climate change, with rising water temperatures and increasing ocean ...

Learning from nature's bounty: New libraries for drug discovery

Natural products, or their close derivatives, make some of our most potent medicines, among which macrocycles with their large carbon-rich ring systems are one class. The size and complexity of macrocycles has made it difficult ...
