Simple syntheses of phosphoric (4) and carboxylic (6) acid anhydrides have been elaborated by means of solid potassium carbonate in phase-transfer catalytic acylation. Behavior of various acid chlorides, phosphoric (1), sulfonic (2), and carboxylic (8), have also been studied toward potassium carbonate in the presence of lipophilic quaternary ammonium salt.
