Synthesis of fluorine-containing prenylated benzophenones

In this study, an effective route to synthesize fluorine-containing prenylated benzophenones was developed. Friedel–Crafts acylation and electrophilic aromatic substitution reactions were the key reactions of this synthesis to achieve these fluorinated prenylated benzophenones. The use of DBU in the prenylation step achieved only the C-prenylated benzophenones, whereas K2CO3 produced the C- and O-prenylated benzophenones.
