Herein, a molecular ruthenium‐phosphine catalyst system for the effectivebase‐free methyl formate production from carbon dioxide is described. In detail, the novel [Ru(N‐triphosCy)(tmm)] complex, bearing sterically demanding cyclohexyl groups in the triphos‐ligand structure, enabled in combination with the Lewisacid Al(OTf)3 the selective transformation of carbon dioxide to methyl formate with unprecedented
