The invention discloses a method for preparing beta-perfluoroalkyl enaminoketone. The method specifically comprises the steps that: reactants styrene derivative, amine, perfluoro halide, a catalyst, an oxidant t-butylhydroperoxide, and an additive triethylenediamine are added into an organic solvent; and with a one-step reaction, the product beta-perfluoroalkyl enaminoketone is obtained. The catalyst is acetylacetonate cobalt (II) or acetylacetonate copper (II). According to the method, catalyst reaction activity is high, reaction condition is mild, and reaction time is short. Raw material source is wide, cost is low, and preparation process is simple. Only the one-step reaction in air is needed, and the product can be obtained. The process is safe and environment-friendly. The method is suitable for industrialized production of beta-perfluoroalkyl enaminoketone. |
