Production of aryl ethanols. |
| abstract |
The invention provides a process for preparing aryl ethanols from aryl methyl ketones. The process involves a novel oxidation of the ketone to a dialkylacetal derivative of an aryl glyoxal, which is then hydrolyzed to an aryl glyoxal. The aryl glyoxal is then catalytically hydrogenated to reduce both carbonyl groups simultaneously to yield the aryl ethanol. The process is illustrated by conversion of 4-hydroxyacetophenone to 4-hydroxyphenethyl alcohol. |
