SPECTROPHOTOMETRIC DETERMINATION OF TRACE AMOUNTS OF IODIDE BY ITS CATALYTIC EFFECT ON THE CHLORPROMAZINE-HYDROGEN PEROXIDE REACTION

A catalytic photometric method for the determination of trace amounts of iodide is proposed. In the presence of iodide, chlorpromazine is oxidized by hydrogen peroxide in a sulfuric acid solution to form a red intermediate, which is further oxidized to a colorless compound. The reaction is followed by measuring the increase in the absorbance at 525 nm; the maximum absorbance is obtained on an absorbance-time curve at a given reaction time. Since the maximum value increases with an increase in the iodide concentration, this value is used as a parameter for the iodide determination. Under the optimum experimental conditions (1.0X10(-3) M chlorpromazine, 1.5 M sulfuric acid, 2.0 M hydrogen peroxide, 30-degrees-C), iodide in the range 0.2-10-mu-g l-1 can be determined. The relative standard deviations are 0.8, 2.6 and 4.2% for 6.0, 2.0 and 0.6-mu-g l-1 iodide, respectively. Although iodate shows the same catalytic effect as iodide at the same concentration as iodine, free iodine shows a somewhat lower catalytic effect. The procedure has been applied to the determination of iodide in natural water samples.

MOLECULAR DYNAMICS SIMULATION OF A MOLTEN MIXTURE OF LITHIUM BROMIDE AND LITHIUM IODIDE

Molecular dynamics simulation for a 1:5 molar mixture of lithium bromide and lithium iodide was carried out with Born-Mayer-Huggins type pair potential. The self-exchange velocity of the iodide ion is greater than that of the bromide ion although the iodide ion is heavier than the bromide ion. This anion Chemla effect is explained from the difference in the barrier height of the potential function which the bromide ion or the iodide ion feels from the lithium ion. The pair distribution functions, the angular correlation functions and the velocity autocorrelation functions are also examined.

Copper-catalyzed etherification of aryl iodides using KF/Al2O3: An improved protocol

A simple and efficient method for the coupling of aryl iodides with aliphatic alcohols and phenols that does not require the use of alkoxide bases is described. This C-O bond forming procedure shows that the combination of air stable CuI and 1,10-phenanthroline in the presence of KF/Al2O3 comprises an extremely efficient and general catalyst system for the etherification of aryl iodides. Different functionalized aryl iodides were coupled with alcohols and phenols using this method.

Carbonyl allylations by allylic chlorides utilizing a reduction of tin(IV) iodide to triiodostannate(II) species with iodide sources

Carbonyl allylations by allylic chlorides either with tin(IV) iodide and tetrabutylammonium iodide (TBAI) in dichloromethane or with tin(IV) iodide and sodium iodide in 1,3-dimethylimidazolidin-2-one at room temperature produced the corresponding homoallylic alcohols. The carbonyl allylations probably proceeded via the reduction of tin(IV) iodide to triiodostannate(II) species with iodide sources such as TBAl and Nal, which led to the construction of a tin(IV)-catalytic cycle based on regeneration of tin(IV) iodide via the transmetalation of homoallyloxytriiodotin to homoallyloxytrimethylsilane with iodotrimethylsilane.
