YieldReaction ConditionsOperation in experiment
99% With C37H28N8O*2Cl(1-)*Pd(2+); potassium carbonate; In ethanol; at 70℃; for 2h; General procedure: Arylhalide (5.0 mmol) and phenylboronic acid (5.0 mmol), K2CO3 (5.0 mmol) and X-Pd3L (0.005 mol% Pd loading) were added to a solutionof 12 mL EtOH under ambient atmosphere. The mixture was stirred at 70 C for 2 h. After cooling, H2O (10 mL) was added into the resultant mixture and the product was extracted by ethyl acetate (3 × 10 mL). The organic phase was combined and dried over Na2SO4. After removal of solvent, the product was dried at 60 C. In most cases, the products are pure (analyzed by 1H NMR spectroscopy) because it is an equal stoichiometric reaction and the substrates are completely converted into product. If the product is impure, the purification can be performed ona silica gel chromatography (hexane:ether = 60:1 as an eluent). All products were confirmed by 1H and 13C NMR and compared with literatures (see SI). For the recycled experiment, the xerogel catalyst was recovered by centrifugation and washed with EtOH (3 × 4 mL) after reaction, then dried in air.
86% With palladium; potassium carbonate; In methanol; acetonitrile; at 20℃; for 2h; General procedure: To a freshly prepared solution of PdNPs (10 mL, 0.02 mmol), required amount of K2CO3 (2 mmol) was added followed by aryldihalides/ arylhalide (1 mmol) and arylboronic acid (3 mmol)/diboronic acid (0.75 mmol). Then, the reaction mixture was stirred at room temperature in open atmosphere. The reaction was monitored by TLC and was stopped after the complete consumption of starting material. The desired product got precipitated out which was separated by filtration and extracted with chloroform. The chloroform layer was evaporated to get the terphenyl in pure state.
