In this communication, the decarboxylation of methyl formate to methane was achieved using a ruthenium triphos bis acetate catalyst and lithium iodide as an additive in THF, with yields up to 95 %. The reaction involves methyl iodide and lithium formate as key intermediates. A small scope of alkyl formates was tested and the reaction proved applicable to ethyl formate and benzyl formate. A scale-up reaction showcased the production of 132 mL of methane from 0.36 mL of methyl formate, the latter serving as a liquid surrogate containing 27 wt% methane.
