Abstract
The present invention provides a process for the preparation of aryl carboxylic acids by the carbonylation of diaryliodonium salts. The diaryliodonium salts are reacted with carbon monoxide in the presence of a zero-valent palladium in a hydrocarbon acid reaction medium to prepare the aromatic carboxylic acids.
