실험 절차

0.86 g (0.00767 mol) of potassium tert-butoxylate and 2.55 g (0.00714 mol) of methyltriphenylphosphonium bromide are initially introduced. The apparatus is cooled to 0° C., and the solids are dissolved using 15 ml of THF (abs.). The mixture is stirred for 30 min, while, in a second apparatus, 2.31 g (0.0039 mol) of 4-[9-(4′-carbazol-9-ylbiphenyl-4-yl)-9H-carbazol-2-yl]benzaldehyde is weighed out and dissolved using 25 ml of THF. At 0° C., solution 2 is added to solution 1 and stirred for a further 1.5 h. The mixture is taken up in CH2Cl2 and washed by shaking three times with water. The combined organic phases are dried over magnesium sulfate, filtered off and evaporated to dryness. Column chromatography with toluene give 2.1 g (93%) of clean substance.
