YieldReaction ConditionsOperation in experiment
92.6% With tetrakis(triphenylphosphine) palladium(0); potassium carbonate; In 1,2-dimethoxyethane; water; at 90℃; for 12h;Inert atmosphere; General procedure: Potassium carbonate (51.4 mmol, 3 eq.) is dissolved in -25 ml of deionized water, the solution is degassed with N2 for 30 mm. Glyme (175 ml) is degassed in a oomL 3- necked round bottom flask with N2 for 30 mm. The flask is then charged with boronic ester (17.14 mmol, i eq.), bromophenyldialkylphosphine oxide (17.99 mmol, 1.05 eq.)and tetralds(triphenylphosphin)palladium(o) (0.51 mmol, 0.03 eq.) under a positive nitrogen pressure. The degassed potassium carbonate solution is added using a syringe, nitrogen purged reflux condenser is attached to the flask and a reaction mixture heated to 90 C with stirring for 12 h. The mixture is allowed to cool down to the room temperature, a precipitate is collected by filtration, washed with water, methanol, driedin vacuum at 40 C to give a crude product, which could be further purified by recrystallization or tnturation with appropriate solvents Final punfication is achieved by sublimation in a high vacuum.
