YieldReaction ConditionsOperation in experiment
96% With aluminum (III) chloride; In dichloromethane; at 20℃; j0099j 154.0 g (1.0 mole) of biphenyl and 148.0 g (1.0 mole) phthalic anhydride were dispersed in 800 ml of methylene dichloride. Then 226.0 g (2 moles) of aluminum trichloride was added in portions, under water cooling, so that the temperature did not exceed 20C. Then the mixture was allowed to stir overnight at room temperature and became a greenish- bluish color. Then the reaction mixture was poured slowly, under stirring, into a mixture of 3.0 liters of water, 500 g of crushed ice, and 400 g of sulfuric acid. During the addition, the bluish color disappeared and a white precipitate was formed, which was separated by filtration, washed with 4 x 300 ml of water, and dried.Yield: 291.Og (96% of theory) Characterization:GC-purity: 98%Melting point: 232-233CGC-purity: 99%Mass Spectroscopy (m/z): 374 (M(+) -1 + 73(trimethylsilane) 359 (100%), 285,228, 181,152, 73UV-spectroscopy: 2 max = 286 nm (ethanol)
89% With aluminum (III) chloride; In neat (no solvent); for 1h;Milling; General procedure: A mixture of aromatic substrate (0.46 mmol), phthalic anhydride (1 equiv) and AlCl3(2.5 equiv.) was placed in a 16 mL stainless steel jar, together with one stainless steel 12 mm ballin Retsch MM400 ball mill. The mixture was ball milled for 1 hour at 30 Hz. The reaction mixturewas suspended in water, pH adjusted with conc. HCl. The precipitate was collected by filtrationand subjected to column chromatography on silicagel using dichloromethane to remove unreactedaromatics, then product was eluted with DCM/10% methanol.
