In connection with a study of a number of anticancer compounds which, presumably also act as inhibitors of free-radical polymerization, eight classes of compounds were studied as to their inhibitory properties. The classes studied were unsaturated hydrocarbons, phenolic compounds, quinones, amines, stable free-radicals, sulfiir compounds, carbonyl compounds, and metallic salts. The most effective inhibitors, of those evaluated, were cupric acetate and cupric resinate, followed by /runs-1,3,5-hexatriene, hydroquinone, benzoquinone, and diphenylamine as modest inhibitors. Among the low-activity inhibitors were 2,2-diphenyl-1-picrylhydrazyl, benzene thiol, and crotonaldehyde [70]. 

Large scale separation of rare earths involve use of EDTA and NTA with the resin in cupric state. Zinc form resin has also been used with NTA. In some cases HEDTA is useful and in some cases superior to EDTA and NTA since resins in hydrogen form can be used. EDTA is probably the best reagent for the separation of the entire series of rare earths. 

The Chitopearr resin was packed in a glass column (inner diameter 1. 4 cm, bed height 4.3 cm). The column was first equilibrated with a 20 mM MES buffer containing 20 mM NaCI and 10 mM 2-mercaptoethanol. Then 60 ml of the MES buffer containing metal ion was applied at the flow rate of O.S ml/min. Adsorption capabilities of the ligands were examined for cadmium, gallium, cupric, zinc, or nickel ion. After the column was washed with MES buffer, the adsorbed metal ion was eluted with the MES buffer (pH of which was adjusted to pH 2.0). In order to examine effects of pH on the adsorption, pH of the MES buffer was varied from pH S to pH 9. The eluted solution was collected as several fractions of 10 ml each, and the metal concentration of each fraction was determined with atomic adsorption analysis (SAS 7S00A, Seiko Instruments, Japan). Total amount of the eluted metal ion was defined as the adsorbed metal ion on the resin. The total amount of the adsorbed metal ion was divided by the total amount of immobilized protein to calculate the number of metal molecules bound to one mole of the protein. The adsorption experiments were carried out multiple times, and the maximum experimental error was 25%.

The absorption of copper from the bowel can be influenced by a number of inorganic substances. Anions, which have a tendency to form highly insoluble salts with copper under the conditions prevailing in bowel contents, tend to reduce the absorption of copper. Sulfide is the best known of these. Cupric sulfide is poorly absorbed by rats and pigs (B21, S23). Addition of sulfides to the diet markedly reduces copper absorption in animals (D5) and man (C5). Of the cations, molybdenum is known to influence copper retention in animals. It is suspected that molybdenum influences the membrane transport of copper in such a way that absorption is decreased and excretion increased (D6). For details of this problem the reader is referred to Underwood s monograph (U2) and a recent review by Mills (M25). Problems of this nature have not yet been encountered in man. Oral doses of potassium sulfide and certain ion-exchange resins are used to reduce the absorption of copper in certain pathological conditions in man (C5). 

This method makes use of commercially available, thin-layer plates coated with a cation-exchange resin in the sodium form the sodium ions can readily be exchanged for other cations by immersing the plate in an appropriate salt solution. Cupric, calcium, and lanthanum acetates have been used to introduce cations that complex readily. The plate is then developed with water as the irrigant. Compounds that form complexes with the cations are retained and have low values those that complex weakly are... 

Many initiator-accelerator systems that contain accelerators other than amine have been suggested for vinyl pol3rmerization, but only a few have been employed in dental resins. Substitution of p-toluenesulfinic acid, alpha-substituted sulfones and low concentrations of halide and cupric ions for tertiary amine accelerators, yields colorless products (43-48). Most of these compounds have poor shelf-life. They readily oxidize in air to sulfonic acids which do not activate polymerization. Lauroyl peroxide, in conjunction with a metal mercaptide (such as zinc hexadecyl mercaptide) and a trace of copper, has been used to cure monomer-pol3rmer slurries containing methacrylic acid (49-50). Addition of Na salts of saccharine to monomer containing an N,N-dialkylarylamine speeds up pol)rmerization (51). 

Paquette was one of the first to apply the Wacker oxidation in the total synthesis. In his synthesis of 18-oxo-3-virgene, a constituent of the waxy surface resins of tobacco, a Wacker oxidation was deployed to convert a terminal alkene to the corresponding methyl ketone.59 In an efficient total synthesis of ( )-laurene (77), alkene 75 was oxidized to keto-aldehyde 76 at ambient temperature.60 In Smith s total synthesis of calyculin, a modified Wacker oxidation with substoichiometric cupric acetate transformed terminal alkene 78 to methyl ketone 79 without concurrent acetonide hydrolysis.61,62... 

Note that the cupric ion is shown to be associated with two resin functional groups, releasing two sodium ions. Half the number of moles of doubly charged copper is equivalent on the basis of charge to sodium or hydrogen. If the copper were present as singly charged cuprous ion, the equivalents would contain equal numbers of moles.
