ABSTRACT:
Aromatic ethers/phenols are acylated, characteristically into hydroxy- and/or alkoxyaromatic alkylketones, and in particular, are acylated in the para-position relative to an alkoxy substituent borne by the aromatic nucleus, by reacting/condensing same with an acylation agent, for example acetyl chloride or acetic anhydride, in the presence of a catalytically effective amount of a bismuth halide, or a precursor compound that generates, in situ, a bismuth halide.
