Reaction Steps

Palladium acetate (11.4 mg 0.05 mmol), AgOAc (217 mg 1.3 mmol), 3-bromobenzoic acid (201 mg, 1.0 mmol), 3,5-dichloroiodobenzene (819 mg, 3.0 mmol) and acetic acid (200 μL) were combined and heated at 120° C. for 5.5 h. After purification light tan solid was obtained, 183 mg (53%), mp 182-186° C. (isooctane). Rf-0.38 (1/9 ethyl acetate-dichloromethane). 1H NMR (300 MHz, acetone-d6) δ 7.32 (br s, 2H), 7.36 (d, J-8.4 Hz, 1H), 7.44 (br s, 1H), 7.79 (d, J-8.4 Hz, 1H), 8.05 (br s, 1H). Carboxylate proton signal was not observed. 13C NMR (75 MHz, acetone-d6) δ 122.2, 127.6, 127.7, 133.2, 133.3, 134.6, 135.0, 139.4, 144.5, 166.7. A signal for one aromatic carbon could not be located. FT-IR (neat, cm1) υ 1699, 1299, 857. Anal. calcd for C13H7BrCl2O2 (346.00 g/mol): C, 45.13; H, 2.04. Found: C, 45.17; H, 2.04. The 1H NMR and 13C NMR spectra are shown in FIGS. 27A&B, respectively.
