Potassium Carbonate → 2,6-Dimethyl-4'-trifluoromethyl-biphenyl-4-carbaldehyde

Participants

Reaction Steps

Trifluoro-methanesulfonic acid 4-formyl-2,6-dimethyl-phenyl ester (4 g, 14.2 mmol), 4-trifluoromethyl-phenylboronic acid (5.4 g, 28.4 mmol), tetrakis(triphenylphosphine)palladium (1.64 g, 1.42 mmol), LiCl (1.8 g, 42.6 mmol), and K2CO3 (5.9 g, 42.6 mmol) are placed in a flask. The system is purged with nitrogen, followed by the addition of toluene (20 ml) and water (5 ml). The resulting mixture is refluxed overnight, loaded on silica gel directly, and purified by silica gel column chromatography, eluting with EtOAc/hexanes to afford 3.8 g (96%) of the titled compound as a white solid. 1H-NMR.
