  • Lewis acids have recently been shown to enable stereocontrol in photochemical cycloadditions, a difficult task due to the reactivity of excited-state compounds. Here the authors show that chiral Brønsted acids are competent chromophore activators in [2+2] cycloadditions, forming diastereomers disfavored in similar Lewis acid catalyzed photochemical reactions.

  • To mark the occasion of Nature Chemistry turning 10 years old, we asked scientists working in different areas of chemistry to tell us what they thought the most exciting, interesting or challenging aspects related to the development of their main field of research will be — here is what they said.

  • The report of a light-activated catalyst that dictates the three-dimensional shape — the stereochemistry — of molecules formed in an organic reaction suggests a new strategy for controlling such reactions using visible light. See Letter p.100

  • Direct coupling methods, which do not require substrate prefunctionalization, are highly desirable for the construction of complex molecular scaffolds. Now, a photochemical method has been developed for the direct decarboxylative coupling of carboxylic acids with diverse nitrogen, oxygen and carbon nucleophiles, taking advantage of the photochemistry of copper(II) carboxylate complexes assembled in situ.

  • Sunlight is potentially an ideal green 'reagent' for chemical synthesis, but poor absorption by organic substrates makes direct solar photochemistry generally inefficient. Here, recent progress in the use of the simple organometallic complexes to harness the power of the sun is summarized, and prospects for the future of this exciting field highlighted.
