Reaction Steps
0.82 g (3.0 mM) of 2-octylindan-5-boronic acid, 0.36 g (1.5 mM) of 2,5-dibromothiophene, 2 ml of ethanol, 4 ml of benzene, 4 ml of 2M-sodium carbonate aqueous solution and 0.12 g of tetrakis (triphenylphosphine)palladium (O) were mixed and heat-refluxed for 1 hour under stirring. After the reaction, the reaction mixture was poured into ice water to precipitate a crystal. The crystal was recovered by filtration under reduced pressure and purified by silica gel column chromatography (eluent: hexane/toluene=2/1) and recrystallized from a mixture solvent (toluene/methanol) to obtain 0.74 g (1.37 mM) of 2,5-bis(2-octylindan-5-yl)thiophene (Yield: 91%). ##STR326##
