In the chemical reaction process,reaction time,type of solvent,can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product.An updated downstream synthesis route of 538-58-9,1,5-Diphenylpenta-1,4-dien-3-one, as follows.538-58-9
General procedure: In a general procedure, dibenzylidene acetone (1 mmol), N,N-dimethylbarbituric acid/barbituric acid/thiobarbituric acid(1 mmol) and 4 mL of ethanol:water (1:1) were taken in a 50 mL round-bottomed flask. 10 mol% of tetrabutyl ammonium bromide (TBAB) was added to the mixture, and the contents were stirred. The reaction mixture was refluxed and the progress of the reaction was monitored by TLC using ethyl acetate:petroleum ether (30:70) as eluent for disappearance of active methylene compounds. After completion of the reaction, the reaction mixture was allowed to cool to room temperature and diluted with water (5 mL). The solid obtained was filtered at pump and washed with water:ethanol (2:1). The product was recrystallized with ethanol. The products were characterized by their spectral data.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. 538-58-9, We look forward to the emergence of more reaction modes in the future.
