    • Experimental Procedure: 3,3′-Bis(indolyl)phenylmethane (1a, 1 mmol, 322 mg) was taken up in a round-bottom flask containing MeCN (5 mL, I2 (2 mol, was added and the mixture refluxed for 20 min. The obtained solid was filtered, dried, and recrystallized from a mixture of DMF-CHCl3. The structure of the compound obtained was identified from spectroscopic data and elemental analysis. 6,12-Diphenyl-5,11- dihydroindolo[3,2-b]carbazole (2a) White solid, mp 350°C Yield 80, 326 mg, Rf, 0.84 [EtOAc (7, PE, IR (KBr, 3394 (NH stretch, 3062 (w, 3019 (w, 1492 (w, 1456 (s, 745 (s, 702 (m) cm -1. 1H NMR (300 MHz, DMSO-d6, δ, 6.72-6.77 (t, 2 H, J, 7.41 Hz, 6.87-6.92 (t, 2 H, J, 7.32 Hz, 6.98-7.0 (d, 4 H, J, 7.71 Hz, 7.05-7.08 (d, 2 H, J, 7.83 Hz, 7.14-7.19 (t, 6 H, J, 7.14 Hz, 7.58 (s, 2 H, 9.93 s, 2 H, NH, 13
