Reaction Steps

Carbazole (1.80 g, 10.9 mmol), 4,4′-dibromobiphenyl (0.75 g, 2.4 mmol), and potassium tbutoxide (2.24 g, 20 mmol) were dissolved in dry toluene and heated at 135° C. for 24 h. The solution was filtered and the solvent was removed in vacuo, the residue was dry-packed on SiO2 and chromatographed using 10% acetone in hexanes to afford (0.08 g, 6%) of the product. 1H NMR (CDCl3) δ 8.22-8.16 (m, 4H), 7.93-7.65 (m, 8H), 7.56-7.49 (m, 8H), 7.47-7.28 (m, 4H). 13C NMR (CDCl3+DMSO-d6) δ 142.1, 140.8, 140.7, 139.0, 138.3, 137.3, 130.5, 128.5, 127.3, 126.1, 126.0, 125.9, 125.6, 123.4, 120.3, 120.2, 120.0, 109.7. EI MS m/z 484 [M+], m.p.=244-246° C.
