With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.52522-40-4,Tris(dibenzylideneacetone)dipalladium-chloroform,as a common compound, the synthetic route is as follows.

0.1127g (0.4871mmol) of Me-TtBQ, 0.1755g (1.218mmol) of dmfu and 0.2101g (0.2030mmol) of [Pd2(DBA)3¡¤CHCl3] were dissolved under inert atmosphere (Ar) in 30ml of anhydrous acetone. The mixture was stirred for 60min and eventually treated with active charcoal for 5/10min and filtered on Celite filter. The resulting yellow solution was dried under vacuum and the residual treated with diethyl ether, filtered off, washed with diethyl ether in excess and dried under vacuum. 0.1452g (yield 75percent) of the title compound was obtained as pale yellow microcrystals.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.52522-40-4,Tris(dibenzylideneacetone)dipalladium-chloroform,as a common compound, the synthetic route is as follows.

0.1624 g (0.4076 mmol) of 1,2-bis(diphenylphosphine)ethane, 0.1671 g (1.159 mmol) of dmfu and 0.2002 g (0.1934 mmol) of [Pd2(DBA)3*CHCl3] were dissolved under inert atmosphere (Ar) in 30 ml of anhydrous acetone and vigorously stirred for 60 min. Owing to the progressive dissolution of [Pd2(DBA)3*CHCl3], the violet color of the mixture gradually disappeared and the concomitant precipitation of the scarcely soluble pale yellow complex 1j was observed. The solution was dried under vacuum, the residue dissolved in CH2Cl2, treated with activated charcoal and filtered on a celite filter. The clear pale yellow solution was concentrated under vacuum and the title complex precipitated by slow addition of diethylether. Complex 1j was filtered off on a gooch, washed with diethylether and dried under vacuum. 0.2027 g (yield 81percent) of the title complex 1j as a pale yellow solid was obtained. 1H NMR (300 MHz, CDCl3, T = 298 K, ppm) delta: 2.11-2.61 (m, 4H, CH2P), 3.40 (s, 3H, OCH3), 4.33-4.42 (m, 2H, CH=CH), 7.32-7.53 (m, 16H, PPh), 7.79-7.85 (m, 4H, PPh). 13C{1H} NMR (CDCl3, T = 298 K, ppm selected peaks) delta: 26.7 (m CH2, CH2P), 50.5 (CH3, OCH3), 52.9 (m, CH, CH=CH), 173.7 (C, CO). 31P{1H} NMR (CD2Cl2, T = 298 K, ppm) delta: 39.0.

Stage 2: Stage 1 material (8.50 g) and 3,5-bis(4-tert-butylphenyl)phenyl-1-boronic acid pinacol ester (15.50 g) were dissolved in toluene (230 mL). The solution was purged with nitrogen for 1 h before 2-dicyclohexylphosphino-2′,6′-dimethoxybiphenyl (66 mg) and tris(dibenzylidene)dipalladium (75 mg) were added using 10 mL of nitrogen-purged toluene. A 20wtpercent solution of tetraethylammonium hydroxide in water (60 mL) was added in one portion and the mixture as stirred for 20 h with the heating bath set to 105 ¡ãC. T.L.C. analysis indicated all the stage material had been consumed and only one fluorescent spot was observed. The reaction mixture was cooled and filtered into a separating funnel. The layers were separated and the aqueous layer extracted with toluene. The organic extracts were washed with water, dried with magnesium sulphate, filtered and concentrated to yield the crude product as a yellow/orange solid. Pure compound was obtained by column chromatography eluting with a gradient of ethyl acetate in hexanes followed by precipitation from DCM/methanol. HPLC indicated a purity of 99.75percent and a yield of 80percent (11.32g). 1H NMR (referenced to CDCl3): 7.83 (3H, d), 7.76 (6H, s), 7.73 (3H, s) 7.63 (12H, d) 7.49 (12H, d), 7.21 (3H, dd), 6.88 (3H, d), 4.28 (9H, s), 2.25 (3H, m), 1.98 (3H, m), 1.4-1.5 (57H, m), 1.23 (3H, m), 0.74 (9H, t)
