SYNTHESIS AND CHEMISTRY OF K2S2O8 ABSTRACT In this experiment‚ a sample of K2S2O8 was prepared by the electrolysis of an aqueous solution of H2SO4 and K2SO4. The peroxodisulfate anion‚ S2O82-‚ was also observed for its ability to serve as a counterion for precipitation by preparing a copper (II) complex by reacting hydrated copper (II) sulfate with ammonium peroxodisulfate in the presence of pyridine. This same ability‚ coupled with its strong oxidizing ability allowed for stabilization of

has several advantages: It gives only the trans product; it uses a much milder base that is easier to handle; and it gives a water soluble byproduct which is easy to separate from the product. The reason that these advantages occur is a change in the structure of the ylide. Instead of a tripheylphosphine ylide‚ we use a diethylphosphonate ylide. The protons are much more acidic and its byproduct is negatively charged. The reason why we chose to create trans-stilbene is become of its many practical

Though cis-platin is highly effective‚ its counterpart trans-platin is counterintuitively not (7). Trans-platin is highly reactive with the environments that lead to reaching the DNA‚ and this reactivity results in the totality of the administered compound becoming deactivated prior to reacting with the DNA (9). Also the DNA lesion caused by cis-platin on the 1‚2 intrastrand crosslinks between adjacent purines is an act that trans-platin cannot do when looking from a stereochemical perspective (9)

Multistep Synthesis of Tetraphenylcyclopentadienone In this laboratory experiment a synthesis was performed through several separate steps. The purpose of the experiment was to synthesize tetraphenylcyclopentadienone from benzaldehyde and to run reactions on carbonyl containing compounds. There was a total of three steps that led up to the synthesis of the final product‚ tetraphenylcyclopentadienone. The first step of the experiment was the condensation of benzaldehyde to yield

Synthesis of trans-9-(2-Phenylethenyl)anthracene Introduction The purpose of this experiment was to convert carboxyl compounds into alkenes. While this reaction yields both the E and Z isomers‚ it is preferred over other reactions due to the lack of uncertainty of where the double bond is positioned. Also the stability of an ylide determines which isomer is the major product. 1 Experimental: Compounds Benzyltriphenylphosphonium chloride 9-Anthraldehyde 50% Aqueous NaOH DCM Product Formula weight

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:
