  • Nickel organic compounds play a crucial role in organic and bioinorganic chemistry, however, their potential role in prebiotic chemistry is not well understood. Here, the authors identify the formation of a nickel bis(dithiolene) from nickel sulfide under an acetylene-containing volcanic hydrothermal experimental environment and reveal its role in the transformation of acetylene to acetaldehyde.

  • Various fatty acids and aldehydes can be synthesized from acetylene and carbon monoxide by nickel sulfide catalysts under volcanic hydrothermal conditions compatible with aqueous early earth conditions, however, their chemical complexity remains underexplored. Here, the authors use 13C-labelling together with untargeted ultrahigh-resolution mass spectrometry to categorize carboxylic acid functional groups, revealing C2-addition driven compound diversity as well as new sulfur containing classes.

  • Aldehydes can be formed under extraterrestrial conditions, however, the synthesis of aldehydes on early Earth remains largely unclear. Here, the authors report the formation of acetaldehydes and higher condensation products starting from a gaseous mixture of acetylene and carbon monoxide over nickel sulfide containing water with various pH-values under hydrothermal conditions.
