Selective two-phase-hydrogenation of sorbic acid with novel water soluble ruthenium complexes
摘要:
Neutral and cationic water soluble Cp*-ruthenium-complexes of the type [Cp*Ru(CO)Cl(PR3)] and [Cp*Ru(CO)(PR3)]CF3SO3 (R = CH2OH, (CH2)(3)OH, Ph-m-SO3Na) have been synthesized for the first time and have been used as catalysts in two-phase-hydrogenations. The neutral complexes have been fully characterized. But the cationic complexes which have not been isolated are effective catalysts for the selective hydrogenation of sorbic acid in water/n-heptane leading to the formation of cis-3-hexenoic acid and trans-3-hexenoic acid.
