| titleOfInvention | Process for para-hydroxyalkylation of hydroxylated aromatic compounds |
| abstract | The present invention relates to a process for the para-hydroxyalkylation of hydroxylated aromatic compounds. The invention relates to a process for the preparation of optionally substituted p-hydroxymandelic compounds and more particularly the preparation of p-hydroxymandelic acid and of 3-methoxy-p-hydroxymandelic acid. The subject of the invention is a process for the para-hydroxyalkylation process of a hydroxylated aromatic compound in which the para position of the hydroxyl group is free, characterized in that the said compound is condensed with a compound carrying a carbonyl group, in the presence of a quaternary ammonium hydroxide. |
