Finalnie uzyskuje się od 0,52 do 0,93 mmol 10,10'-di(mezytylo)-9,9'-bisantracenu o czystości od 95 do > 98% (NMR), co stanowi od 52% do 93% wydajności teoretycznej w stosunku do wyjściowego 10,10'-dibromo-9,9'-bisantracenu.The subject of the present invention is a method for obtaining 10,10'-di(mesityl)-9,9'-bisanthracene by carrying out a Suzuki-Miaury coupling process with 2,4,6-trimethylphenylboronic acid (mesitylboronic acid), such that in such a way that in a reactor capable of obtaining a strictly anoxic and anhydrous atmosphere, 10,10'-dibromo-9,9'-bisanthracene and the following components are placed in a proportion of 1.0 mmol of 10,10'-dibromo-9,9' bisanthracene: 2,4,6-trimethylphenylboronic acid (mesitylboronic acid) in the amount of 2.0 to 8.0 mmol, trisodium phosphate or, more preferably, tripotassium, in the amount of 2.0 to 15.0 mmol, catalyst precursor in the form of Pd(II) salt ), for example [Pd(acac)<sub>2</sub>] or more preferably [Pd(OAc)<sub>2</sub>], in an amount of 0.05 to 0.5 mmol, a phosphine ligand in a dialkyl biaryl phosphine form selected from:. 2-dicyclohexylphosphine-2',4',6'-triisopropylbiphenyl (XPhos) or 2-dicyclohexylphosphine-2',6'-dimethoxybiphenyl (SPhos) or most preferably 4-(Anthracen-9-yl)-3-(t-butyl) -2,3-dihydrobenzo[d][1,3]oxaphosphole (AntPhos), in the amount of 0.1 to 1.0 mmol, dried molecular sieves, preferably 4A, in the amount of 0.05 to 0.5 g, after which the reaction vessel is dried under vacuum at a temperature ≤ 60°C together with its contents for at least half an hour, then 10,10'-dibromo-9,9 is added - also in a proportion of 1.0 mmol - in an inert gas atmosphere -bisanthracene - from 20 to 200 ml of anhydrous liquid low boiling aromatic hydrocarbon, preferably 60 ml of anhydrous toluene, and the mixture is heated in a closed system at a temperature of from 80 to 130°C, in a strictly anoxic and anhydrous atmosphere, for at least 6 hours after this time, the reaction mixture is cooled to a temperature below 40°C and filtered on a funnel, filtering out the solids of the post-reaction mixture, including palladium particles, and then the volatile fractions are evaporated on a vacuum evaporator in a typical way, and then the solid residue obtained is separated the crude product is obtained by column chromatography on silica gel using a mixture of a liquid, low-boiling aromatic hydrocarbon with a low-boiling aliphatic ester in a volume ratio of 50:1 to 5:1 as the eluent. Finally, 0.52 to 0.93 mmol 10 is obtained, 10'-di(mesityl)-9,9'-bisanthracene with a purity of 95 to > 98% (NMR), which is from 52% to 93% of theory relative to the starting 10,10'-dibromo-9,9 '-bisanthracene.
