Turning a problem to advantage: CO2, a contributor to global warming, was converted into the valuable resource CH3OH by adding it to 2,2,6,6-tetramethylpiperidine and B(C6F5)3 in toluene under H2 (1–2 atm), heating the mixture at 160 °C, and vacuum distillation. CH3OH was formed via the complex shown (C blue, N purple, O red, B orange, F green) as the sole C1 product.
