Abstract The synthesis of dimethoxymethane (DMM) by a multistep reaction methanol with carbon dioxide and molecular hydrogen is reported. Using the catalyst [Ru(triphos)(tmm)] in combination Lewis acid Al(OTf) 3 resulted versatile catalytic system for various dialkoxymethane ethers. This new provides first synthetic example selective conversion into formaldehyde oxidation level, thus opening access to structures using this important C 1 source.
