Abstract: Microwave-assisted O-alkylation reactions of carboxylic acids, such as aryloxyacetic acids, 4-chlorobenzoic acid, (un)substituted furoic acids, and benzofuroic acid, with (un)substituted ω-haloacetophenones in dry media under phase-transfer catalysis are described. 2-Oxo-2-arylethyl carboxylates are expeditiously synthesized by this method in high yield using tetrabutylammonium bromide as catalyst.
