Production of hydroxy arylophenones |
| abstract |
Production of a hydroxy arylophenone by reacting an aromatic carboxylic acid Ar(--CO 2 H) p where Ar is an aromatic radical, (--CO 2 H) is an aromatic carboxylic acid group, and p is 1 or 2 with an aromatic compound H--Ar'--OH where Ar' is an aromatic radical and --H and --OH are aromatically bound para to each other in a benzenoid ring, in the presence of an alkyl sulphonic acid, particularly methane sulphonic acid, to produce a hydroxy arylophenone of formula Ar(--CO--Ar'--OH) p where the carbonyl and hydroxyl groups are para to each other in the hydroxyl-containing benzenoid ring of Ar'. The production of the hydroxy arylophenone proceeds through the intermediate ester (H--Ar'--O--CO--) p Ar and the production of the hydroxy arylophenone starting from the ester is also claimed. |
