Catalytic hydrogenation of 1-hexene with RuCl2(TPPMS)(3)(DMSO) Part II: Ionic liquid biphasic system
RuCl2(TPPMS)(3)(DMSO) (complex (1)) is very soluble in the ionic liquid 1-n-butyl-3-methylimidazolium hexafluorophosphate (BMI.PF6). Complex (1) catalyzes 1-hexene hydrogenation (500 psi H-2 and 100degreesC) in a two-phase system, with 80% conversion in 24 h, with little substrate isomerization. Changes in catalytic behavior with temperature, pressure, time and substrate/catalyst relation are presented. Complex (1) shows good stability and can be reused several times with little activity loss.
