Cascade Catalysis for the Homogeneous Hydrogenation of CO<sub>2</sub> to Methanol
This communication demonstrates the homogeneous hydrogenation of CO<sub>2</sub> to CH<sub>3</sub>OH via cascade catalysis. Three different homogeneous catalysts, (PMe<sub>3</sub>)<sub>4</sub>Ru(Cl)(OAc), Sc(OTf)<sub>3</sub>, and (PNN)Ru(CO)(H), operate in sequence to promote this transformation
Tandem Amine and Ruthenium-Catalyzed Hydrogenation of CO<sub>2</sub> to Methanol
This Communication describes the
hydrogenation of carbon dioxide
to methanol via tandem catalysis with dimethylamine and a homogeneous
ruthenium complex. Unlike previous examples with homogeneous catalysts,
this CO<sub>2</sub>-to-CH<sub>3</sub>OH process proceeds under basic
reaction conditions. The dimethylamine is proposed to play a dual
role in this system. It reacts directly with CO<sub>2</sub> to produce
dimethylammonium dimethylcarbamate, and it also intercepts the intermediate
formic acid to generate dimethylformamide. With the appropriate selection
of catalyst and reaction conditions, >95% conversion of CO<sub>2</sub> was achieved to form a mixture of CH<sub>3</sub>OH and dimethylformamide
