The Carbon2Polymer project involves a multistep reaction sequence for the non‐phosgene synthesis of the high‐value polymer precursor toluene‐2,4‐diisocyanate (TDI) starting from carbon dioxide. The present study of the oxidative carbonylation revealed that for the intermediate toluene‐2,4‐dicarbamate (TDC) the productivity is highest with Pd@ZrO 2 , followed by Pd@CeO 2 . As one of the side products which are formed in parallel and consecutive reactions the methylene‐bridged dimer “TDCCH2TDC” (5) has a promising potential for industrial application.
