  • Interstellar aldehydes are essential intermediates to form biomolecules necessary for the origins of life, but their formation mechanisms have remained elusive. Here, the authors elucidate the formation pathways of biologically relevant aldehyde, lactaldehyde, and its isomers in interstellar ice analogs composed of carbon monoxide and ethanol.

  • Helicenes represent key building blocks leading eventually to carbonaceous nanostructures. Here, exploiting [4]-helicene as a benchmark, the authors present a synthetic route to racemic helicenes via a vinylacetylene mediated gas phase chemistry with aryl radicals involving ring annulation.

  • Small polycyclic aromatic hydrocarbons (PAHs) are thought to be nucleation sites for the growth of Titan’s haze layers. Using laboratory experiments and electronic structure calculations, Zhao et al. show that small PAHs can by synthesized by rapid, barrierless reactions in Titan’s low-temperature environments.
