The systems Ru₃(CO)₁₂·nL, (L = PPh₃, CH₃CN, (EtO)₃Si(CH₂)₃NH₂; n = 0–3, 15) have been employed as catalysts and/or catalyst precursors for thermal hydrogenation and isomerization reactions of 1-octene under moderate reaction conditions (1 atm at 70°C or below). In the hydrogenation reaction the system Ru₃(CO)₁₂/15CH₃CN showed the highest activity, with turnover numbers up to 1000. For this system the kinetics indicated that the hydrogenation occurs via a lower nuclearity catalytic species formed by fragmentation of the mother cluster. On the other hand the isomerization reaction occurs, after a 10–20 min induction period, by higher-nuclearity catalytic species. The isomerization gave trans-2-octene only, and none of the cis-isomer. The effects of other factors on the rates of hydrogenation and isomerization reactions are described.
