Metal-Free Reduction of CO2 to Methanol Using Boranes at Ambient Conditions Promoted by Boron-Appended N-Heterocyclic Nitrenium Catalysts.
The chemical reduction of carbon dioxide (CO2) into value-added C1 building blocks, particularly under sustainable, metal-free conditions, remains a profound challenge in modern catalysis. Herein, we report robust boron-tethered N-heterocyclic nitrenium (NHN) catalysts for the reduction of CO2 under ambient conditions...
