Abstract

The palladium-catalyzed carbonylation of diaryliodonium tetrafluoroborates and tosylates (toluene-p-sulfonates) in the presence of methanol and phenol afforded aromatic esters at room temperature under one atmosphere of carbon monoxide. However, carbonylation of diaryliodonium triflates and bromides in methanol afforded 4-iodophenyl-substituted methyl esters.
