A 75% CO conversion is obtained after four hours at 20 °C and 1 atm CO for the water‐gas reaction when the Ru II complex 1 is used as homogeneous catalyst. The optimum reaction conditions were found to be 50 °C and 15 atm CO; the turnover number is then 350 mol CO 2 /H 2 per mole of catalyst per hour. 1 is by far the most effective homogeneous catalyst for the water‐gas reaction; the heterogeneously catalyzed reaction is usually carried out at 400–460°C and 200 atm CO.
