실험 절차

50 g of bromo-9,9-dimethyl-9H-fluorene (183 mmol), 38 g of p-phenylaniline (220 mmol), 1.5 g of DPPF (2.7 mmol), 0.5 g of palladium(II)acetate and 45 g of sodium tert-butoxide (486 mmol) are heated at the boil in 1.5 l of toluene under a protective-gas atmosphere for 18 h. The mixture is subsequently partitioned between toluene and water, and the organic phase is washed three times with water, dried over Na2SO4 and evaporated in a rotary evaporator. The residue which remains is recrystallised from heptane/ethyl acetate. The yield is 33 g (91.5 mmol, 50%).
