The Reaction of Arylazo Aryl Sulfones with Carbon Monoxide and Nucleophiles Catalyzed by the Palladium(0) Complex

Article abstract of DOI:10.1246/bcsj.62.605

The reaction of arylazo aryl sulfone (1) with carbon monoxide in the presence of the palladium(0) catalyst affords substituted benzoic acid in a good yield, together with minor yields of diaryl ketone and biaryl.The reactions of 1 with carbon monoxide and such nucleophiles as alcohols and amines under similar conditions give esters and amides, respectively.
