Synthesis and Coordination Chemistry of Water-soluble Phosphines: Application to Ru-Catalyzed Hydration of Nitriles in Aqueous and Biphasic Media
… water-soluble catalysts for aqueous and biphasic hydration of nitrile. A series of upper-rim modified PTA derivatives were prepared by reaction of lithiated PTA with various electrophilic substrates, including aldehydes, ketones, imines and CO2. Monodentate ê1-P and bidentate ê2-P,O and …

Charakterisierung und rationale Immobilisierung von Lipasen in biphasischen Reaktionssystemen
… aspects on optimal pH and enzyme behaviour in biphasic reaction media are still not well-known. Such information is highly desired for the rational process design. Therefore, the influence of the pH in lipase-based esterifications in biphasic media was studied. For Candida rugosa and …

Hydrierung im invertierten Zweiphasensystem scCO 2/H 2 O
Catalysis using an inverted scCO2/H2O biphasic system where the catalyst is immobilized in scCO2 as stationary phase and the substrate and product are contained in the aqueous phase, offers an interesting alternative to classical biphasic systems and enables the conversion of polar substrates, …
