Researchers at Ruhr University Bochum, Germany, have discovered a new synthetic pathway with which they can produce a specific organic compound from the simple molecule carbon monoxide (CO), namely anionic ketenes. These were previously only known as reactive intermediates, and therefore couldn’t be used as defined reagents. The Bochum-based researchers produced anionic ketenes that were so stable that they could be isolated. Unlike previous methods, which can produce higher-value compounds from simple molecules, this approach doesn’t require any expensive or toxic metals.
