Anodic Copper

The electrochemical oxidation of anodic copper or silver (= M) into non-aqueous solutions of RSH (R = alkyl, axyl) gives MISR as insoluble materials in high yield. In the presence of 1,10-phenanthroline (= L), the products are MISR•phen for M = Cu, but not Ag. Gold resists oxidation under such conditions, and AuISR (R = n-C4H9, C6H5) was obtained in only poor yield. The crystal structure of the solvated dimeric adduct [Cu(SC6H4CH3-o)•phen]2•CH3CN is triclinic, with a = 10.682(3) Å, b = 11.729(4) Å, c = 15.608(5) Å, α = 76.87(2)°, β = 76.35(2)°, γ = 68.07(2)°, V = 1742(1) Å3, Z = 2 and space group [Formula: see text]. The structure is based on a folded Cu2S2 ring with an unusually short Cu—Cu distance of 2.613(3) Å Each copper atom has CuS2N2 pseudo-tetrahedral stereochemistry, with Cu—S = 2.337 Å(av) and Cu—N = 2.10 Å(av).

The cadmium β-diketonate complexes Cd(RCOCHCOR′)2 (R = CH3, R′ = CH3; R = CF3 R′ = CH3, i-C3H7, i-C4H9, t-C4H9, C6H5, 2-naphthyl) can be prepared in good yield by the direct room temperature electrochemical oxidation of the metal into a solution of the parent diketone in acetonitrile. Adducts of the type Cd(RCOCHCOR′)2L (L = 2,2′-bipyridine, 1,10-phenanthroline, N,N,N′,N′-tetramethylethylenediamine) can be prepared insitu, or by subsequent addition of the ligand to the electrolytic solution. X-ray studies show that the molecular structure of both Cd(acac)2phen and Cd(CF3COCHCOC6H5)2phen is based on a CdO4N2 kernel, distorted from octahedral stereochemistry by the bite of the ligands.
