Process for preparing phenethanol ethers by the reduction of corresponding phenylglyoxal acetals |
| abstract |
Substituted phenethanol ethers are prepared by the catalytic reduction of corresponding substituted phenylglyoxal acetals. The catalytic reduction is carried out by reacting a substituted phenylglyoxal acetal with hydrogen in the presence of an acid catalyst and a metal catalyst. Certain substituted phenylglyoxal acetals, and more particularly, 4-hydroxyphenylglyoxal dialkyl acetals are prepared by reacting 4-hydroxyacetophenone with a primary or a secondary alkyl alcohol in the presence of a hydrogen ion (H+) source and a nitrosonium ion (NO+) source. |
