Electric Literature of 538-58-9, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.538-58-9, Name is 1,5-Diphenylpenta-1,4-dien-3-one, molecular formula is C17H14O. In a Patent£¬once mentioned of 538-58-9
A high-purity (dibenzylidene acetone) two palladium (0) of the preparation method (by machine translation)
The invention discloses a high-purity (dibenzylidene acetone) two palladium (0) of the preparation method, the method comprises: a, under the nitrogen atmosphere, the ligand dibenzylidene acetone, two palladium chloride and anhydrous sodium acetate into a mixing state in anhydrous ethanol heating reaction, obtained after filtering the solid double-(dibenzylidene acetone) palladium (0); b, under the nitrogen atmosphere, obtained in the step a solid double-(dibenzylidene acetone) palladium (0) into a mixing state of acetone in the reaction, washing of objects after being filtered, washed and removing of drying, to obtain three (dibenzylidene acetone) two palladium (0). The invention uses absolute ethanol, dibenzylidene acetone, two palladium chloride and anhydrous sodium acetate first preparing double-(dibenzylidene acetone) palladium (0), then the acetone solution processing to obtain three (dibenzylidene acetone) two palladium (0), the prepared three (dibenzylidene acetone) two palladium (0) of relatively high purity.
