10.6% | With tris-(dibenzylideneacetone)dipalladium(0); tri-tert-butyl phosphine; sodium t-butanolate; In toluene; at 100℃; for 24h; | A catalyst consisting of tris(dibenzylideneacetone)-dipalladium(0) (Pd2dba3) (2.747 g, 3 mmol) and tris(tert-butyl)phosphine (18.2 mL, 18 mmol) dissolved in 100 mL toluene and preformed by stirring for 15 min at room temperature was added to <strong>[25032-74-0]bis(3-bromophenyl)methanone</strong> (20.4006 g, 60 mmol), bis(3-aminophenyl)methanone (6.3675 g, 30 mmol), and sodium tert-butoxide (17.298 g, 180 mmol) dissolved in 400 mL toluene. This mixture was stirred for 24 h at 100 C and then cooled to room temperature, filtered off, and washed with CH2Cl2. After removing the solvent, the product was purified by chromatography on silica gel with petroleum ether/CH2Cl2 as eluent and recrystallized from tetrahydrofuran/methanol to obtain the desired pure product (yield = 1.81 g, 10.6%). 1H NMR (500 MHz, CDCl3): δ 7.66 (dt, J = 7.6 Hz, 1.3 Hz, 6H), 7.44 (t, J = 7.8 Hz, 6H), 7.37 (ddd, J = 8.0 Hz, 2.1 Hz, 1.1 Hz, 6H), 6.92 (t, J = 1.8 Hz, 6H). 13C NMR (126 MHz, CDCl3): δ 194.94, 148.99, 138.10, 131.04, 130.92, 129.20, 125.70. Anal. calcd (%) for C39H24N2O3: C 82.38, H 4.25, N 4.93; found: C 82.21, H 4.19, N 4.98. APCI-MS (m/z): [M]+ calculated for C39H24N2O3, 568.63; found, 569.5. |
