Synthesis
Weigh PdCl2, dissolved in 1:1 hydrochloric acid, weigh triethylphosphine, dissolved in 200 mL of anhydrous ethanol, add PdCl2 solution under stirring, heated to boiling, reflux reaction for 4 h, to get a yellow precipitate, filtered while hot, washed with anhydrous ethanol for 2 times, and then washed with ethyl ether for 2 times, 50% vacuum drying for 2 h, to get the bis(triethylphosphine)palladium(II) chloride, the yield 98.5%.
