  1. a 1 mmol substrate, 50 °C, p(H2) = 20 bar, 5 mg Ru@SiCN catalyst (0.03 mol% active metal), 1 mL water, 20 h
  2. b Yields determined by GC and GC-MS using dodecane as internal standard
  3. c 50 °C, 3 bar H2 pressure, 24 h
  4. d 100 mmol substrate, 50 °C, p(H2) = 20 bar, 200 mg Ru@SiCN catalyst (0.01 mol% active metal), 10 mL water, 24 h. The reactor was pressured again to 20 bar after half of the reaction time
