The Triflic Acid-Catalysed Deacylation and Decarboxylation of Polymethylbenzenecarbonyl Derivatives under Mild Conditions

Article abstract of DOI:10.1246/bcsj.62.599

Sterically hindered acylarenes are deacylated to arenes in good yields on heating in boiling 1,2-dichloroethane containing a catalytic amount of triflic acid and water.Hindered arenecarboxylic acids undergo decarboxylation under the same conditions to give arenes in high yields.
