Abstract
4-(2',4'-Difluorophenyl)acetophenone was synthesized from 2',4'-difluorophenylboronic acid and 4-bromoacetophenone via the Suzuki cross-coupling mediated by the ligand-free Pd(Ⅱ)complex.The yield of 4-(2',4'-difluorophenyl)acetophenone was 98.7% at 35 ℃ over a reaction time of 20 min.The structure of 4-(2',4'-difluorophenyl)acetophenone was characterized by IR,1HNMR,and the single crystal X-ray diffractometry.
