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.
General procedure: 9-Amino(9-deoxy)-epi-quinine (6.5 mg, 0.02 mmol), divinyl ketone 1 (0.1 mmol), nitromethane (262 muL, 3.0 mmol), Proton-sponge (4.3 mg, 0.02 mmol) and benzoic acid (4.9 mg, 0.04 mmol) were dissolved in chlorobenzene (238muL). After stirred at 40 oC for 144 h, the reaction mixture was purified by flash chromatography on silica gel (EtOAc/petroleum ether).
