DMSO (Wako Pure Chemicals Inc.) was distilled twice from 4A molecular sieves(Wako) under reduced pressure. Dicyanobis(l,10-phenanthroline)iron(II) [Fe(CN)2(phen)2] was synthesized by mixing 0.03 mol of phen and 0.01 mol of ammonium iron(II) sulfate hexahydrate in 400 cm3 of water, followed by the addition of KCN (0.15 mol). The resulting crude crystals were then dissolved in 30 cm3 of concentrated sulfuric acid followed by the addition of ldm3 of water. Dicyanobis(l,10-phenanthroline)iron(III) nitrate was obtained by the oxidation of corresponding iron(II) complex with concentrated nitric acid. The perchlorate salt was obtained by the addition of sodium perchlorate to the nitrate solution. Analytical grade hydroquinone, catechol, and L-ascorbic acid (Wako) were used without further purification. 

Epoxidation. The stereoselectivity for epoxidation of cw-dihydroxycyclohexene derivatives shows protecting group and solvent dependence. The conversion of neopentylideneimines of a-amino esters to the oxaziridines (with MCPBA) followed by treatment with ammonium iron(II) sulfate hexahydrate accomplishes A-formylation. ...

The iron content of tFdx is detemiined by atomic absorption spectroscopy at 248 nm using a Nanolab AG aa/ae spectrophotometer (Video 12 E). The spectrophotometer is calibrated with standard solutions of iron(ll) sulfate hexahydrate. Correlation of the iron content with the amount of protein determined by an amino acid analysis of the same probe reveals the presence of 4.2 mole of iron per mole of tFdx. This result and H NMR measurements show that recombinant tFdx purified under aerobic conditions contains a single and intact 4Fe-4S cluster. In contrast, the native 4Fe-4S cluster of the ferredoxin from the hyperthermophilic archaeon Pyrococcusfuriosus, the amino acid sequence of which is 50% identical to that of tFdx, decays rapidly to the 3Fe-4S form in the presence of oxygen. This difference is probably due to the replacement of one of the cysteine residues of tFdx coordinating the cluster by an aspartate in P. furiosus ferredoxin.

For the approach detailed above to be successful, the metal binding domain must form robust complexes, yet retain synthetic flexibility. Although substituted phenanthroline and bipyridine easily form self-assembled receptors (12), the substitution stability of terpyridine (Fig. 2) makes this ligand more suited for the creation of libraries. The choice of metal also permits some flexibility in library creation. Iron complexes form easily through the addition of ammonium iron(II) sulfate hexahydrate, but can be cleaved by the addition of chelating guests (11,13), Cobalt complexes are also easily formed using cobalt(II)...

Nitrates. Iron(II) nitrate hexahydrate [14013-86-6], Fe(N03)2 6H20, is a green crystalline material prepared by dissolving iron in cold nitric acid that has a specific gravity of less than 1.034 g/cm. Use of denser, more concentrated acid leads to oxidation to iron(III). An alternative method of preparation is the reaction of iron(II) sulfate and barium or lead nitrate. The compound is very soluble in water. Crystallisation at temperatures below — 12°C affords an nonahydrate. Iron(II) nitrate is a useful reagent for the synthesis of other iron-containing compounds and is used as a catalyst for reduction reactions. 

Little is known concerning the chemistry of nickel in the atmosphere. The probable species present in the atmosphere include soil minerals, nickel oxide, and nickel sulfate (Schmidt and Andren 1980). In aerobic waters at environmental pHs, the predominant form of nickel is the hexahydrate Ni(H20)g ion (Richter and Theis 1980). Complexes with naturally occurring anions, such as OH, SO/, and Cf, are formed to a small degree. Complexes with hydroxyl radicals are more stable than those with sulfate, which in turn are more stable than those with chloride. Ni(OH)2° becomes the dominant species above pH 9.5. In anaerobic systems, nickel sulfide forms if sulfur is present, and this limits the solubility of nickel. In soil, the most important sinks for nickel, other than soil minerals, are amorphous oxides of iron and manganese. The mobility of nickel in soil is site specific pH is the primary factor affecting leachability. Mobility increases at low pH. At one well-studied site, the sulfate concentration and the...
