実験手順

A three-necked flask was charged with 2,8-dibromodibenzofuran (39.12 g, 120 mmol), carbazole (20.07 g, 120 mmol), K3PO4 (50.94 g, 240 mmol), copper iodide (11.43 g, 60 mmol), 1,2-trans-diaminocyclohexane (20.55 g, 180 mmol), and 1,4-dioxane (120 ml), and the mixture was refluxed for 9 h. After the reaction, the reaction product solution was cooled to room temperature and extracted with CH2Cl2 using a separatory funnel. The extract was dried over anhydrous magnesium sulfate, filtrated and concentrated. The obtained solid product was purified by a column chromatography (hexane:toluene=8:2). The above operations were all performed in an argon atmosphere (16.0 g, 32% yield),
