Tetrahydrofuran → 2,4-Bis-(4-tert-butylphenyl)-6-(4'-vinylbiphenyl-4-yl)-1,3,5-triazine

Participants

Reaction Steps

2.0 g (0.0040 mol) of 2-(4-bromophenyl)-4,6-bis-(4-tert-butylphenyl)-1,3,5-triazine and 0.8878 g (0.006 mol) of vinylphenylboronic acid and 0.050 g (0.0432 mmol) of Pd(PPh3)4 are initially introduced. After addition of 26 ml of sodium carbonate solution and 54 ml of THF, the mixture is brought to reaction under reflux for 24 h. For work-up, the mixture is filtered through Celite and taken up in ethyl acetate. The organic phase is extracted a number of times with water. The solvent of the combined organic phases is removed completely. A recrystallisation is carried out from chloroform/ethanol, and subsequent column chromatography is carried out with hexane:ethyl acetate. After the column chromatography, 1.6 g (76%) of clean substance are isolated.
