YieldReaction ConditionsOperation in experiment
97% at 20℃; for 16 h; Inert atmosphere To a 500 mL reaction was added 10 g (1,5-cyclooctadiene) palladium dichloride, the reaction flask was replaced with a nitrogen atmosphere,19.6 g of di-tert-butyl-4-dimethylaminophenylphosphine prepared in Example 1 and 200 mL of anhydrous tetrahydrofuran were added, and the mixture was stirred at room temperature for 16 hours,There is a solid precipitation,Filtration and drying gave a pale yellow powder product bis (di-tert-butyl-4-dimethylaminophenylphosphine) palladium chloride 24. 1 g,The yield was 97percent (yield based on (1,5-cyclooctadiene) palladium dichloride)The purity of the product was 99.8percent by XY-1A intelligent element analyzer.

YieldReaction ConditionsOperation in experiment
1445 g at 20℃; for 9.5 h; Inert atmosphere Take a dry 10L three-neck reaction flask, dry nitrogen is fully replaced and under nitrogen flow protection,Add 5.5 L of anhydrous tetrahydrofuran, stir and add 540 g of bis(acetonitrile)palladium dichloride.The obtained ligand di-tert-butyl-4-dimethylaminophenylphosphine was further reacted for 30 minutes, and a yellow solid was precipitated. After the reaction was continued for 9 hours at room temperature,After filtration, the filter cake was dipped in anhydrous tetrahydrofuran, drained and dried in a vacuum oven at 60 ° C.Obtaining a yellow crystalline powdery target product, namely dichlorodi-tert-butyl-(4-dimethylaminophenyl)phosphine palladium, yielding 1440 g to 1445 g,Elemental analysis showed that the product content exceeded 98.0percent, the palladium content exceeded 15.0percent, and the palladium calculated yield was 97.7percent to 98.1percent.
