Cover Feature: Decarboxylative Ketonization of Aliphatic Carboxylic Acids in a Continuous Flow Reactor Catalysed by Manganese Oxide on Silica (ChemSusChem 14/2024)

The Cover Feature depicts the artificial photosynthesis process from CO2 and water to 6‐undecanone, starting with the electrochemical generation of syngas followed by its fermentation to give hexanoic acid and its decarboxylative ketonization to the C11 building block 6‐undecanone. All steps are in the pilot plant stage, as illustrated by the reactor on the right‐hand side. When conducted in flow on a manganese sipernat catalyst, the decarboxylative ketonization step reaches 99.99 % yield at a productivity of 1.1 kg L−1 h−1.
