The Uses of 3-Chlorobenzophenone

3-Chlorobenzophenone is a reagent in the preparation of pharmaceuticals such as antitumor kinesin spindle protein inhibitors.

Research

Li et al. research the influence of the chloro substituent position on the triplet reactivity of benzophenone derivatives. The 3-chlorobenzophenone (3-Cl-BP), 4-chlorobenzophenone (4-Cl-BP), and 4,4′-dichlorobenzophenone (4,4′-dichloro-BP) triplets exhibit similar hydrogen abstraction ability as has been found previously for the parent BP triplet. In IPA, the 3-Cl-DPK, 4-Cl-DPK, and 4,4′-dichloro-DPK radicals were observed and reacted with DMK radical, most likely at the para-position to form a para-LAT. In a MeCN: H2O/1:1 aqueous solvent, these DPK radicals were also observed but with a slower formation rate. All of these results indicate that the 2-chloro substituent reduces the hydrogen abstraction ability of the substituted BP triplet, not as may be expected that an electron-withdrawing group could increase its photoreduction activity[1].
