Reaction Steps

A mixture of 6.6 g (28 mmol) of 1,4-dibromobenzene, 15.1 g (32 mmol) of 2-(10,10-dimethyl-10H-indeno[1,2-b]triphenylen-12-yl)-4,4,5,5-tetra methyl-1,3,2-dioxaborolane, 0.32 g (0.28 mmol) of tetrakis(triphenylphosphine) palladium, 22 ml of 2M Na2CO3, 60 ml of EtOH and 130 ml toluene was degassed and placed under nitrogen and then heated at 90° C. for 12 h. After finishing the reaction, the mixture was allowed to cool to room temperature. Than 500 ml MeOH was added, while stirring and the precipitated product was filtered off with suction and the residue was purified by column chromatography on silica (hexane-dichloromethane) to give product 7.4 g (53%) as a white solid.
