Synthesis and Ir Analysis of Trans-[Bis(Inosinato)Palladium(Ii)]
Synthesis and IR Analysis of trans-[Bis(inosinato)palladium(II)]

Abstract

In this lab we synthesized trans-[Bis(inosinato) palladium(II)] for IR analysis. After completion of the reaction 84.4% of the product was collected. IR spectrum of the product and inosine was analyzed to determine how the inosine is bonded to the metal, palladium. From the IR analysis, it was determined that when inosine reacts with palladium, a shift of about 65 cm-1 in the carbonyl stretch was observed.

Introduction:

In this experiment, trans-[Bis(inosinato)palladium(II)], was synthesized. The general reaction equation for the reaction is shown below: KOH
(1) K2[PdCl4] + 2 inosine trans-[Pd(inosine-H+)2] + 2KCl + 2HCl

The IR spectrum of the product and inosine was analyzed to compare the location of the carbonyl bond when inosine interacts with a metal such as palladium. This study is important because the interaction of metals with an organic base purine derivative, such as inosine has great biological significance.1 For instance, many cofactors in various enzymatic reactions are both metal ions and nucleosides, such as organic base purine derivatives.1 By studying the infrared data for the boinding of insoine to the metal atom, the interactions between the purine derivative and metal can be studied.

Experimental:

All reagents and solvents used were purchased from commercial suppliers. All solvents and reagents used in this experiment were used as received. To obtain IR spectra, Thermo Scientific Nicolet IR100 FT-IR spectrometer was used.

General Procedure 1: Preparation of trans-[Bis(inosato)palladium(II)]¹

Inosine (0.17 mmol) was placed in a beaker containing 5 mL of water and a magnetic stirring bar. Another solution was prepared by dissolving potassium tetrachloropalladate(II) (0.1 mmol) in 1 mL of distilled water. This solution was added slowly dropwise with a pipet to the beaker. The two solutions were

    Chemists often find a method to determine the level of “greenness” of a chemical reaction, or its “atom economy”. A higher atom economy is preferable because a greater amount of the reactants will be present in the product as opposed to the byproduct.1 A Suzuki reaction is classified as an organic, coupling reaction that includes boronic acid and a halide that are catalyzed by a palladium complex under basic conditions. Other palladium- catalyzed coupling mechanisms include the Heck and Stille reactions. Palladium typically exists in the oxidation states of 0, +2, and +4. PdCl2 is usually the starting compound for several other heterogeneous palladium catalysts such as Pd/C and Pd/BaSO4.1 Suzuki coupling is an efficient way to…

    In this experiment, 1,2-dibromo-1,2-diphenylethane is synthesized from the bromination of trans-stilbene through the addition of hydrobromic acid (HBr) and hydrogen peroxide (H2O2). This is a green reaction because bromine is generated in situ from the reaction of hydrobromic acid and hydrogen peroxide as shown in Figure 2.…

    Ethanol (100ml), potassium hydroxide (8.065g, 2.568mmol) and water (5ml) were added in order to 2,4,5-triphenyl-1H-imidazol (0.9402g, 3.17mmol). The mixture was stirred until clear before it was cooled to 5 ºC. A solution of potassium ferricyanide (3.0021 g, 9.085mmol), water (250ml) and ethanol (100ml) was prepared and added dropwise into the mixture ensuring the temperature did not rise above 10 ºC. A grey precipitate was isolated from the yellow mixture through vacuum filtration and washed with water (50ml x 5) and 50% aqueous ethanol. The mixture was dried under vaccuum suction and the melting point was determined. Yield: 0.85g, 90.8% m.p-199.8-200.3ºC. A portion of the dimer (0.0305 g, 0.0514mmol) was quantitatively dissolved in 25ml of toluene. The solution was left for 60min until colorless. The UV-Vis spectra was recorded for the colorless sample. The solution was irradiated using a lamp resulting in a purple solution and the UV-Vis spectrum was retaken.

    An IR spectra was obtained for fluorene. Unfortunately, the experimental IR spectra did not even remotely match the IR spectra from the literature values. For instance, in the literature IR, a peak at 2956 cm−1 and 1477 cm−1 represent the C-H and C=C bond, respectively. These peaks are not present on the experimental IR. Also,…

    A theoretical mass of 1140 mg and an experimental mass of 263 mg resulted in a 23.1% yield. This low percent yield is most likely due to error in the experiment. The potassium permanganate test was positive for the presence of a double bond in the product as brown precipitate formed along with the discoloration of the solution. An IR spectroscopy of the product was also performed. Results of the IR absorptions of this experiment were compared to the IR absorptions of standard functional groups as identified by the University of Puget Sound. Three main absorption bands were formed at 3373.46 cmˉˡ, 1635.71 cmˉˡ, and 1101.39 cmˉˡ. The absorption band at 3373.46 cmˉˡ is between the ranges of 3200-3600 cmˉˡ which indicates the presence of an alcohol. Ideally, this reaction would only result in 4-methylcyclohexene. However, the presence of alcohol signifies a partial or incomplete reaction. The absorption band at 1635.71 cmˉˡ is between the ranges of 1620-1680 cmˉˡ which correlates to a carbon double bonded to a carbon. This result coincides with the potassium permanganate test as it expresses the existence of an alkene product. The last absorption band falls between the ranges of 1050-1150 cmˉˡ which denotes a carbon bonded to an alcohol. Again, this could be due to an incomplete or partial reaction. There is a strong unidentified peak before 1000 cmˉˡ which could indicate a carbon bonded hydrogen in an alkene as it…
