Selective and Mild Deacylation of Hindered Acylarenes with Aqueous Trifluoroacetic Acid

Article abstract of DOI:10.1055/s-1985-31413

Sterically hindered acylarenes are deacylated to arenes in quantitative yields on heating in boiling 85percent trifluoroacetic acid.Hindered arenecarboxylic acids undergo decarboxylation under the same conditions to give arenes in high yields.
