Ethylenebis( e/ /-phosphine)palladium(0) complexes are air-sensitive but can be kept for months, when dry and pure, under inert gas in a refrigerator. They are soluble in organic solvents like benzene and toluene palladium may precipitate from the solutions, especially that of the triphenylphosphine complex, unless they are saturated with ethylene. Therefore, the complexes may be crystallized from toluene-diethyl ether mixtures saturated with ethylene. 

The ethylenebis(tricyclohexylphosphine)palladium(0) and ethylenebis(tri-u-tolyl phosphite)palladium(0) complexes dissolve in diethyl ether when argon is passed through the suspension. Upon evaporation of these solutions in vacuo, the corresponding bis(tert-phosphine)palladium(0) complexes are obtained. ...
