Dismutation of Hg22+ catalyzed by colloidal gold

Colloidal gold in acetonitrile catalyzes the disproportionation of Hg 22+ to Hg2+ and Hg0. This catalysis is apparently initiated by the amalgamation of the gold particles, which is indicated by a concomitant change of the plasmon absorption of colloidal gold.

Reactivity of palladium dithizonate with Lewis acids and bases

Palladium cannot be removed from palladium dithizonate (Pd(Dz)2) by thiocyanate, cyanide (pH 8), or ethylenediaminetetraacetate (pH 3-8) or by copper perchlorate, silver perchlorate, mercury(II) chloride, or mercury(II) perchlorate in acidic solutions. Palladium dithizonate does react with mercury perchlorate in perchloric acid as well as silver perchlorate at pH 2-4. The products of the reaction with mercury perchlorate studied in four organic solvent systems were examined. The equilibrium constants (-log K) of the postulated reaction 2Pd(Dz)2(o) + Hg2+ + 2ClO4- ? 2Pd(ClO4)Dz(o) + Hg(Dz)2(o) were estimated as 2.79 + 0.19 (CHCl3), 1.35 ± 0.07 (CCl4), 2.56 ± 0.20 (C6H6), and 1.92 ± 0.10 (C6H5Cl). From these, a comparison of the stability of the two palladium dithizonates was made and the cause of the reaction was discussed. The reaction with silver is not a metal exchange but is different from that with mercury, and a mixed-metal secondary dithizonate may be involved.
