Catalytic hydrogenation of 1-hexene with RuCl_2(TPPMS)_3(DMSO).part:aqueous biphasic system

摘要

RuCl_2(TPPMS)_3(DMSO)(complex I)shows good catalytic 1-hexene hydrogenation activity in toluene/water biphasic medium under moderate conditions,reaching 90% conversion in 5 h,with good hydrogenation selectivity and low isomerization products.The effect of various parameters(temperature,H_2 pressure,reaction time,substrate/catalyst ratio,added electrolytes and other additives)on the hydrogenation reaction were studied.Complex(I)shows good stability in the reaction medium and can be reused several times.
