Abstract

Abstract The hydration of aromatic terminal alkynes performed in acetic acid in the presence of catalytic hydrate iron III sulfate, Fe 2 (SO 4) 3· nH 2 O (4–9 mol%), yields the derived aryl methyl ketones with good to excellent yields. Under comparable conditions (18 mol%, 95 C, 24 h), bifunctional substrates were transformed into the monoacetyl or the diacetyl derivatives, depending on the structure of the aromatic diyne. The reaction is compatible ...
