Yield:180037-65-4 95%

Reaction Conditions:

with potassium carbonate in ethanol;water at 80; for 0.166667 h;Green chemistry;Suzuki-Miyaura Coupling;

Steps:

2.2.5. General procedure for the Suzuki-Miyaura cross-coupling reaction

General procedure: The activated Cu-MOF-[Pd] (10 mg), as catalyst, was added to asolution of aryl halide (1 mmol), phenylboronic acid (1.2 mmol,0.15 g) and K2CO3 (1.5 mmol, 0.21 g) in 4 ml H2O-EtOH (1:1,v/v). The reaction mixture was stirred at 80 °C for the requiredtime, progressing of the reaction was monitored by TLC simultaneously.After completion of the reaction, the reaction mixture wascooled to room temperature, centrifuged for separation of the catalystand subsequently dichloromethane (3 x 10 ml) was added tothe reaction vessel. The organic layer was isolated dried over anhydroussodium sulfate and concentrated under reduced pressure.The crude product was purified by column chromatography(nhexane/ethyl acetate) and the pure desired product obtainedby evaporating the solvent.
