Catalytic studies with ruthenium clusters substituted with diphosphines: Part II. Studies with Ru 3(CO) 8(Ph 2PCH 2PPh 2) 2

The catalytic precursor Ru 3(CO) 8(dppm) 2 (dppm=Ph 2PCH 2PPh 2) shows activity with 1-hexene favoring isomerization to cis-2-hexene at lower hydrogen pressures and complete hydrogenation at higher temperature and pressure. The reaction is first order on substrate with a k eff=1.59×10 −3 min −1. Tur...

Summary:The catalytic precursor Ru 3(CO) 8(dppm) 2 (dppm=Ph 2PCH 2PPh 2) shows activity with 1-hexene favoring isomerization to cis-2-hexene at lower hydrogen pressures and complete hydrogenation at higher temperature and pressure. The reaction is first order on substrate with a k eff=1.59×10 −3 min −1. Turnover studies indicate cluster catalysis. The catalytic activity has been demonstrated for other unsaturated organic substrates.
