A novel way of activating an alkali metal for the reduction of CO2 and CO involves dissolving potassium in tetrahydrofuran containing , to give a solution of K as the actual reducing agent.In contact with CO2 or CO, the formal V^-I derivative is immediately re-oxidized to the V⁰ complex and C₁ and C₂ products are formed.
