Hydrochloric Acid → Bis(tri-o-tolylphosphine)palladium(II) Dichloride

Participants

Reaction Steps

Into a 1-l round flask 10.65 g (0.06 mole) of palladium chloride, 300 ml ofwater and 30 ml of concentrated hydrochloric acid were introduced, and after dissolving the solid material uniformly with agitation, 36.5 g (0.12mole) of tri(ortho-tolyl)phosphine were added to the mixed solution, and after further introducing 300 ml of ethanol, the mixed solution was refluxed under heating for 2.5 hours. After cooling, the reaction mixture was filtered and the filtrate was washed with ethanol and then dried, obtaining 41.2 g of yellow bis[tri(ortho-tolyl)phosphine] palladium chloride, ##STR8##(decomposition temperature: 272°-278° C.) in a yield of 99.9%.
