Reaction of Palladium Bisacetylacetonate with Elemental Phosphorus.Effect of Water on the Composition of Palladium Phosphides

摘要

Reaction of palladium bisacetylacetonate with elemental phosphorus in an inert atmosphere is shown to proceed as a redox process forming palladium phosphides of different compositions:PdP2,Pd5P2,Pd_(48)P,and Pd_(12)P_(3,2).The conversion of Pd(acac)2 and the composition of palladium phosphides formed in benzene is established to be affected by water.A tentative scheme of the formation of palladium phosphides is suggested.
