?etinkaya, Yasin,Menzek, Abdullah,Ahin, Ertan,Balaydn, Halis Türker

experimental part, p. 3483 - 3489 (2011/06/11)

(3,4-Dimethoxyphenyl)(2,3,4-trimethoxyphenyl)methanone was synthesized and its bromination was investigated in different conditions. Nine new products (bromophenol derivatives) were isolated in the reactions. These bromophenol derivatives were obtained by selective O-demethylation in its bromination with bromine. The products and their formations were discussed.
