Title: Kinetics and mechanism of the reactions of organochromium complexes with mercury(II) and methylmercury(II) ions

Abstract

Kinetic studies have been carried out on a family of organochromium complexes of the general formula (H/sub 2/O)/sub 5/CrR/sup 2 +/ for the groups R = CH/sub 3/, C/sub 2/H/sub 5/, n-C/sub 3/H/sub 7/, CH/sub 2/C(CH/sub 3/)/sub 3/, i-C/sub 3/H/sub 7/, CH/sub 2/Cl, CH/sub 2/Br, CF/sub 3/, and p-CH/sub 2/C/sub 6/H/sub 4/Z (Z = H, CH/sub 3/, CN, CF/sub 3/, and Br). These cations react with Hg/sup 2 +/ forming RHg/sup +/ and Cr(H/sub 2/O)/sub 6//sup 3 +/, and with CH/sub 3/Hg/sup +/ forming CH/sub 3/HgR and Cr(H/sub 2/O)/sub 6//sup 3 +/. Reaction rates were evaluated as a function of concentration in water at 25.0/sup 0/, and in a few instances in other solvents and at other temperatures. These reactions are believed to follow a bimolecular, electrophilic substitution mechanism.
