摘要

Abstract 2-Acetylresorcinol was prepared in 80–881 yield from 2-acetyl-1, 3- cyclohexanedione by 2-chlorination (excess of NCS in boiling carbon tetrachloride or one equivalent of molecular chlorine in the cold solvent) followed by aromatization in a heated dry solution of hydrogen chloride in dimethylformamide. The scope of the method was extended to the preparation of 2-propionyl-and 2-isobutyrylresorcinol (resp. 791 and 661 ...
