Reaction Conditions:

with potassium tert-butylate in toluene at 130 - 140; for 48 h;Inert atmosphere;Autoclave;regioselective reaction;

Steps:

Synthesis of bis (9H-carbozol-9-yl)-biphenyls 2 (general procedure).
General procedure: Potassium tertbutoxide (1.12 g, 10 mmol) and carbazole (1.67 g, 10 mmol) were added to appropriate dihalobiphenyl 1 (1 mmol) in dry toluene (20 mL). The mixture was heated in a glass autoclave under argon at 130-140 C for 48 h.The resulting suspension was diluted with water to remove inorganic impurities. The organic layer was separated, concentrated to dryness, and chromatographed on silica gel using a 0-10% acetone solution in hexane.
