538-58-9, An elementary termolecular reaction involves the simultaneous collision of three atoms, molecules, or ions.538-58-9, name is 1,5-Diphenylpenta-1,4-dien-3-one. Here is a downstream synthesis route of the compound 538-58-9
General procedure: A mixture of malononitrile (2a) (66 mg, 1 mmol), dibenzylideneacetone (6a) (234 mg, 1 mmol), tributylphosphine (25 mL, 0.1 mmol), and anhydrous CH2Cl2 (5.0 mL) was magnetically stirred in a flask under nitrogen atmosphere at room temperature. The reaction progress was monitored by thin layer chromatography (TLC) until the starting materials were completely consumed. Then, the reaction mixture was diluted with H2O (10 mL) and extracted with Et2O (3×10 mL), the organic phase was washed with brine (10 mL), dried over anhydrous Na2SO4. After the removal of the solvent under reduced pressure, the residue was subjected to chromatography on a silica gel (200-300 mesh) column using petroleum ether/ethyl acetate (4:1) as eluent to afford 7a (286 mg, 95% yield) as a light yellow solid (mp 170-171 C).
