1) Nitration and bromination of resacetophenone and its monomethyl and dimethyl ethers were concluded to occur at 5-position.
2) 5-Bromoresacetophene can be obtained by the hydrolysis of a substance (m.p 84°) of the product obtained from the bromination of resacetophenone monoacetate and melts at 171°.
3) During the methylation of 5-bromo- and 5-nitro-resacetophenone with dimethyl sulfate, the hydroxyl in the ortho-position of the nitro or bromine group was more easily methylated than that ortho to the acetyl group.
