The present invention provides a method for alkoxylating organic compounds comprising contacting an organic compound adapted to be alkoxylated with an alkylene oxide in a reaction vessel under conditions effective to alkoxylate the organic compound. The alkylene oxide is maintained in vapor form during transport to said reaction vessel, during discharge into said reaction vessel, and during contacting of the organic compound with the alkylene oxide. The result is an alkoxylated product containing less flocculant.
enantioselective catalytic kinetic resolution of allylic alcohols through asymmetric isomerization with chiralBINOL derivatives-based alkoxides as bifunctional Brønsted base catalysts were described in the study. A number of chiralBINOL derivatives-based alkoxides were synthesized, and their structure-enantioselectivity correlation study in asymmetric isomerization identified a promising chiral Brønsted
