YieldReaction ConditionsOperation in experiment
42% With tetrakis(triphenylphosphine) palladium(0); potassium carbonate; In toluene; at 100℃;Inert atmosphere; General procedure: A mixture of dibromosilane derivatives A (0.5 g, 1 equiv.),4,4,5,5-tetramethyl-1,3,2-dioxaborolane derivatives B (3 quiv.),Pd(Pd3P)4 (0.2 equiv.) in toluene (30 mL) was added dropwiseK2CO3 (2 M aq. 15 mL) and stirred overnight at 100 C under argon.After the completion of the reaction, the mixture was extractedwith dichloromethane. The organic layers were separated, driedover magnesium sulfate, filtered, and concentrated. The residueswere purified by silica gel column chromatography and thenrecrystallized in acetone or ethanol to give the requisite productsDM4CzDBPSi, DM2CzDBPSi, DP4CzDBPSi. 2.2.2.
