Abstract : The selective decarbonylation of formic acid was achieved under metal-free conditions. Using a liquid chemical looping strategy, the thermodynamically favored dehydrogenation of formic acid was shutdown, yielding a pure stream of CO, with no H2 or CO2 contamination. The transformation involves a two-step sequence where methanol is used as a recyclable looping agent to yield methylformate, which is subsequently decomposed to carbon monoxide using alkoxides as catalysts.
