CLEAN OSMIUM-CATALYZED ASYMMETRIC DIHYDROXYLATION AND AMINOHYDROXYLATION OF OLEFINS IN IONIC LIQUIDS FOLLOWED BY SUPERCRITICAL CO2 PRODUCT RECOVERY

摘要

This invention consists of the description and application of Ionic Liquids (Ils) as a new reaction media for asymmetric dihydroxylation (AD) and aminohydroxylation (AA) of olefins, followed by supercritical CO2 product recovery. Application of ionic liquids and supercritical CO2 in AD or AA reactions allows for simple products recovery without catalyst contamination, in high yield and enantiomeric excess, and it makes the efficient reuse of ionic liquid solvent and the catalytic system possible.
