Summary

γ-Orcacetophenone undergoes deacetylation when condensed with acetoacetic ester in the presence of concentrated H2SO4 or phosphoryl chloride. Acetylation in presence of anhydrous sodium acetate gave a mixture of 5-acetoxy-2: 7-dimethyl-3-acetylchromone, 5-hydroxy-2: 7-dimethyl-3-acetyl chromone, and 4-acetonyl-5-hydroxy-7-methylcoumarin. Thus it differs essentially from its isomer β-orcacetophenone with respect to these reactions.
