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.

Name is Tris(dibenzylideneacetone)dipalladium-chloroform, as a common heterocyclic compound, it belongs to catalyst-palladium compound, and cas is 52522-40-4, its synthesis route is as follows.,52522-40-4

General procedure: To 64.3 mg (0.278 mmol) of TTbQ-Me dissolved in anhydrous acetone (20 ml) in a two necked flask, 30 mg (0.278 mmol) of p-benzoquinone and 120 mg (0.116 mmol) of Pd2DBA3CHCl3 were added in sequence under inert atmosphere (Ar). The resulting mixture was stirred in the dark for 30 min, filtered on a celite filter and evaporated under vacuum to a small volume. Addition of Et2O induces the precipitation of the complex which was filtered off and dried in a desiccator for 5 h. 82.2 mg of the title compound as a red solid were obtained (yield 80percent).

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)
