538-58-9, The molecularity of an elementary reaction is the number of molecules that collide during that step in the mechanism. If there is only a single reactant molecule in an elementary reaction, that step is designated as unimolecular.538-58-9, name is 1,5-Diphenylpenta-1,4-dien-3-one. A new synthetic method of this compound is introduced below.
538-58-9, Step 1. Under a nitrogen atmosphere, add 8 L of absolute ethanol and 0.112 kg of anhydrous sodium acetate to a glass reactor heated in a water bath.When the system temperature was heated to 68 C, 0.92 kg of dibenzylideneacetone obtained in Example 1 was added.After stirring for 30 minutes, add ice to the water bath heater to quickly cool the system down to 60 C.Then, 0.2 kg of palladium dichloride prepared in Example 1 was added and reacted at 60 C for 2 hours.Funnel filtration gave bis (dibenzylideneacetone) palladium (0);
