Fig. 3. Conversion and product distribution in NS hydrogenation over various Rh-based alloys supported on SiO2. Conversion at 0.5 h and selectivity at approximately 50% conversion are shown. Reaction conditions: catalyst, 50 mg (Rh: 3 wt%); NS, 0.5 mmol; solvent, 5 mL ethyl acetate; hydrogen pressure, 1 atm; temperature, 75 °C.
