The invention discloses a preparation method of 1-bromo fluorenone, and belongs to the field of organic chemical synthesis. The method is realized by the following steps of: reacting 2-bromophenyl acetonitrile serving as an initial raw material with nitrobenzene to synthesize 3-(2-bromophenyl)-5-benzoisoxazole; reducing 3-(2-bromophenyl)-5-benzoisoxazole by iron powder to obtain 2-aminobenzene-2'-bromobenzophenone, and finally performing intramolecular cyclization to synthesize 1-bromofluorenone with the content of 99.5% (HPLC) or above and the total yield of 76% or above. The synthesis methodis low in production cost and suitable for industrial production, and 1-bromofluorenone can be used in the fields of organic photoelectric materials, biomedicines and dyes.

We have unfolded a convenient and mild protocol for the synthesis of diaryl ketones via Pd- NHC catalysed carbonylative Suzuki coupling reaction. Notably, this method offers advantages like no use of toxic CO gas, shorter reaction time, high yield, and broad substrate scope. Several sensitive functional groups (like-COMe, -COOMe, -F, -Cl, -Br, -NH2, -CN) are well tolerated in this reaction. In addition, we have also demonstrated a new efficient route for the synthesis of biologically active and pharmaceutically important 2-substituted 3-Aroylquinolin-4(1H)-ones and acridone scaffolds.
