Autocatalytic <i>O</i>-Formylation of Alcohols Using CO₂

Global drive away from fossil feedstock requires the development of synthetic procedures to enhance efficiency CO2 capture and utilization processes using renewable starting materials catalysts. Here, we report an alternative reaction pathway for O-formylation alcohols bio-alcohols, which affords industrially relevant formate esters. Most products, reported herein, derive their carbon atoms exclusively sources. The is catalyzed by formic acid, can also be produced directly captured in reaction. resulting situ acid improves rate, with each catalyst recycling simple filtration, product distillation, reuse residual mixture. Hence, used as a C1 building block simultaneously reduced turn autocatalytically promotes
