With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.7650-91-1,Benzyldiphenylphosphine,as a common compound, the synthetic route is as follows.

Potassium tetrachloropalladate(II) was prepared by the procedure described in [26]. Potassium chloride, 2 equiv, was added to a solution of palladium(II) chloride in 25 mL of distilled water with stirring over a period of 30 min. The mixture was cooled with ice, and yellowish-brown crystals of potassium tetrachloropalladate(II) separated in a few minutes. The crystals were collected by filtration and recrystallized from water containing a few drops of aqueous HCl. The complexes were prepared by adding 2 equiv of the corresponding phosphine in 15 mL of acetonitrile to a solution of 0.326 g of K2[PdCl4] in15 mL of water, followed by stirring. After 30 min, a solution of 2 equiv of N,N-dimethylthiourea in 15 mL of methanol was added, and the mixture was stirred for one hour. The resulting yellow or red solution was filtered, and the filtrate was kept at room temperature for three to five days. Slow evaporation of the acetonitrile-methanol solution afforded solid complex 1-3. The overall reaction is shown in Scheme 1.

General procedure: The heteroleptic Pd(II) complexes were prepared in two steps.In the first step, the Pd(II)-organophosphine complex was preparedby dissolving PdCl2 in methanol, along with 3-4 drops ofconcentrated hydrochloric acid. The desired organophosphinewas dissolved in dry acetone and reacted with PdCl2 solution in2:1 M ratio. The reaction mixture was refluxed for 1 h and the solidproduct was filtered off. In the second step, the dichloromethanesolution of Pd-organophosphine was reacted with dithiocarbamicacid or the potassium salt of the dithiocarbamate ligand in 1:1 Mration under reflux conditions, for 6 h. The resulting golden yellowsolid product was obtained by rotary evaporation. The solid productwas recrystallized in conical flask in 20 mL dichloromethaneand n-hexane in a 4:1 by volume ratio. Golden yellow crystals ofcomplexes 1 and 2 were obtained by slow evaporation at roomtemperature and pressure, while the other complexes did notcrystallize.
