Abstract
The present invention provides a process for the preparation of aryl carboxylic acids and derivatives thereof by the carbonylation of triaryl sulfonium salts. The triaryl sulfonium salts are reacted with carbon monoxide and water or an alcohol or amine in the presence of a triaryl phosphine and a zero-valent metal catalyst selected from palladium or rhodium.
