実験手順

Added into a 500 ml three-necked flask equipped with a condenser under a gaseous stream of argon were 9,10-dibromo-2,6-di(2-ethylhexyloxy) anthracene 0.6 g (1 mmole), dichlorobis(triphenylphosphine) palladium 0.04 g (5 mole %), diisobutylaluminum hydride/toluene solution 0.1 ml (1 M, 0.1 mmole) and THF 10 ml. After the above-mentioned Grignard reagent was added dropwise to them at room temperature, they were heated and stirred overnight. After the completion of the reaction, the reaction solution was cooled with ice water, the precipitates were filtered and washed with methanol 50 ml followed by acetone 50 ml to give the yellow powder 0.56 g. This was identified as Compound 10 by NMR, IR and field desorption mass spectra measurements (FD-MS) (yield 60%).
