Abstract
The catalytic precursor Ru-3(CO)(10)(Ph2PCH2PPh2)(dppm) (dppm = Ph2PCH2PPh2 ) isomerizes 1-hexene mainly to the kinetic product cis-2-hexene at low H-2 pressure, and to n-hexane at higher hydrogenation conditions. The overall first order rate constant on substrate is 0.11 min(-1). The compound hydrog enates other unsaturated groups in good yield. Turnover frequency studies i ndicate cluster catalysis.
