With dichloro(1,1′-bis(diphenylphosphanyl)ferrocene)palladium(II) dichloromethane adduct; anhydrous potassium acetate In 1,4-dioxane at 80℃; for 10h; Molecular sieve; Inert atmosphere;70%
Experimental Procedure
5.5 g of the obtained 2,7-dibromotriphenylene,7.9 g of bis (pinacolato) diboron,4.2 g of potassium acetate,50 ml of 1,4-dioxane previously dehydrated with Molecular Sieves 4 A,0.4 g of [1,1′-bis (diphenylphosphino) ferrocene] palladium (II) dichloride-dichloromethane complex (1: 1) was added to a reaction vessel purged with nitrogen and heated,Followed by stirring at 80 ° C. for 10 hours.After cooling to 50 ° C.,150 ml of chloroform was added,And the mixture was stirred for 30 minutes.Insoluble matter was removed by filtration,The crude product was obtained by concentration.The crude product was purified by column chromatography [carrier: silica gel, eluent: ethyl acetate / n-hexane = 1/5 (v / v)],4.8 g (yield: 70%) of a white powder of 2,7-bis (4,4,5,5-tetramethyl- [1,3,2] dioxaborolan-2-yl) triphenylene was obtained.
