PREPARATION OF HIGHLY REACTIVE METAL POWDERS - PREPARATION AND REACTIONS OF HIGHLY REACTIVE PALLADIUM AND PLATINUM METAL SLURRIES

Reduction of compounds of the type [P(C2H5)3]2MX2 of palladium and platinum with 2 equiv of potassium in ethereal solvents results in highly reactive metal slurries containing insoluble metal and low valent metal phosphine compounds which readily react with a variety of aryl halides to yield the organometallic complexes, trans-[P(C2H5)3]2M(R)X (M = Pd, Pt; R = C6H5, C6F6; X = I, Br, Cl, CN). Such a palladium slurry reacts with allyl bromide to yield P(C2H5)3Pd(C3H5)Br. Reduction of PdI2 with lithium and naphthalene and in the absence of phosphine results in a palladium powder which reacts with C6F5I to yield C6F5PdI, which was isolated as its triethylphosphine adduct. © 1979, American Chemical Society.
