Catalytic hydrogenation of 1-hexene with RuCl_2(TPPMS)_3(DMSO)part II:ionic liquid biphasic system

摘要

RuCl_2(TPPMS)_3(DMSO)(complex(I))is very soluble in the ionic liquid 1-n-butyl-3-methylimidazolium hexafluorophosphate(BMI.PF_6).Complex(I)catalyzes 1-hexene hydrogenation(500 psi H:and 100 deg C)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(I)shows good stability and can be reused several times with little activity loss.
